I have heard that comptech has gone out of business and I am wondering where I can get a cat-back exhaust. Are there any other makers other then comptech?

Hey all, I was actually curious as to how the addition of a CAI & catback affected your fuel economy. Stock, these TLs seem to get around 22-23 mpg mix of city/hwy. I've personally seen my trip meter as low as 16 with backroad driving and as high as 31 on a road trip. The gains from the CAI and catback look great for such simple mods, just curious how they affect the TLs already relatively poopy mileage.

I dynod 258 with a few other mods
04 6MT 258WHP AEM Intake w/IAT relocated to tube, UR Pulley, Outlaw Engineering Thermoblock Spacers, E-Shift Pro Cats

I LOVE the sound of my B18c secondary butterfiles opening after the install of an air intake.!

Exactly that's what I want to know too. I'm newbie on these mods. So any input will be very helpful.
Also, how about the warranty? is it gonna affected or void the manufacture warranty?
So by installing CAI, do we keep the original muffler? even with original mufler it will change the sound?

thanks for the help guys...

Dino the Clown

Acura did not cover problems I have with my engine (Check engine light for a low compression in #6 cylinder) b/c of the mods I had. This sucks but so be it, I rather have my car the way it is and pay for the repair myself. I hope future models will be rear wheel drive. The new models have changed, I dont like the lights in the rear and the odometer style. But this is still my favorite car

d1jey1

That's really sucks big time. Any other user experienve the warranty issue. I haven't done anything yet to my car, but it that means voiding the warranty... hmmm

conan777

I'm interested in the warranty issue also as well as an answer to the question of:

Will a CAI alone change the sound of the car? Will it make it sound meaner, lower kinda like a mustang with no other mods to engine or exhaust? (I know it won't sound like a mustang just using that as an example)

Dino the Clown

The intake will help alot in response and add a few ponies about 10. The sound when you floor it, is much deeper & throaty, sometimes when you tap the gas lightly it will give a little whine like a supercharger would. The engine will also sound much louder than the exhaust when your on it. Its definitely worth it. Others have reported increase gas mileage which makes sense. Get AEM that is what I use & the chrome finish looks nice. Warranty issues??? ask your dealer

Two quick questions, I am a newbie.

I have the CompTec exhaust, but the resonation is very loud, and the wife is bitching about it. Is there anyway to quiet down the inside the cabin resonation, but still keep the 7.5 hp gains?
Also, I have been researching the AEM CAI, but I am wondering how difficult it is to install. I do have the RonJon aero kit.
Thanks for your input.

A lot of people here are saying they are getting X amount of Hp to the wheel.
I understand why they think this because I was one of them until I moved to Australia and when to a tuner shop here.
I purchased a 96 Nissan Skyline and added a few mods, Turbosmart Duel boost control, Apexi power FC handhelp computer,3" Split dump pipe, Full exhaust with 2.5" metal cats and 3" tip; stock turbo, Front Mount Intercooler 600x300x76. My boost is running around 10 on stage 1 and stage 2 is boosting 12.

And my RWKW is 196 and at the chank that is around 275HP.

When you go to a dyno shop the high number is the crank and the lower number is RWHP.

Just ask them?

I had one of the first comptech SC with CAI and Full CT exhaust and only had a 305HP to the crank.

To have 309HP to the wheel is over 400 at the crank and I see none of you guys beating any 400HP cars.

I will get a new turbo and these mods and get 250RWKW and 400HP at the crank

They are new GTT34 hi-flowed turbo with VG30 rear housing, Walbro fuel pump, Z Air flow meter, Sard fuel reg, and maybe nismo injectors.

Please ask your tuner shops about this.

gunner252

maybe i'm misunderstanding what you're trying to say. but in most cases (if not all) the #'s you get from a dyno reading are results at the wheels, not the crank. i've been on a few dyno machines (mustang, dyno jet, etc.) and they all give readings for "at the wheels" not from the crank. the mfgr HP ratings is at the crank, not the wheels.

gunner252

also, 309whp doesnt neccessarily mean you're over 400 hp at the crank. in my experience you normally loose around 20% of your HP in the drivetrain, which would put a 309whp car around 370HP at the crank, not over 400. but maybe you know something i dont....

wizlb

Hey gunner..
When you get a moment ask the dyno guys what your crank HP is?
I have 196RWKW which is aound 230 to 240 @tW and when you convert it to HP it is more like 275 to 280HP.

This is how you have to look at it gunner..
Comptech said there SC will add about 40 to 60 HP gain at the crank.
So when a people says there are getting all this HP at the RW its funny.

But gunner....ask someone..for me...
I had my car dyno in vegas...before leaving to come to sydney and the guy said the numbers are for the crank..i can be wrong.....but 309 @ the rear wheel.....

acura are front wheel drive..

gunner252

i know what you're saying when people think that the HP they are getting at the wheels, is actually at the crank. but when you dyno, in almost all cases, you are getting results for HP at the wheels. i'm speaking of course for the dyno machines that your car gets put on, and your wheels are on the rollers. now, i know that they are dyno machines that can test HP at the crank, but i'm talking about the ones that are tested at the wheels. for example if you look at my dyno chart on this page that's for HP at the wheels.

BKLYNPANMAN
you are nonsense.. leave your ignorance somewhere else... 40 hp??? get informed bro... my #'s are consistent with all the 6mt supercharged tls.. bone stock dynoed is around 230.. do the math asshole.. i had my car dynoed about 4 times.. consistent results..

I was one of the first people on this site to have a SC from Comptech and had it Dyno before most of you had purchased your cars.
Hey BKLYN I am from Vegas and talked on the phone about the power and the problem with the jerking ,,hopefully that had been fixed,,,.

But I have moved to Australia now and I am seeing real hp to the rear wheels here.
A Nissan Skyline GT-R34 with twin turbo get about 175 to the wheels without any mods.

On my car the GTS-T R33 SII 1996 with these mods I am getting @TW 196KW about 220HP.
Mods are: duel boost control, Computer Apexi PowerFC W/ hand control, 3"dump pipe, full exhaust with metal 2" cats and 3" tips, Front mount Intercooler.
I am adding a new HKS GT-RS turbi next week with these to help the fuel, walbrro FP, Z Air Flow meter, Sard Fuel Reg, and maybe Nismo 5500CC inhectors. This will bring my RWKW to 250 to 275RWKW. The additional power can be made if my tuner want to kill my engine and the boost at 21PSI...crazy. so 265RWKW is great.

So Acura said the HP is 270 at the CRANK OR ENGINE they didn't say 270HP at the wheels.
So what is 270 at the crank convert to the wheels and then add the you new gains from your SC and you wll find your HP is no where near 309@TWs

When I contact CT to ask about the power output from the SC I was told just like everyone else it would be 40 to 60 HP gain at the crank not the wheels.

If you guys every come to OZ hit me up, it would be fun to show your a few GT-R34 with 300 and above RWKW.

Til the next time.

Hey down under you have a point there but no need to be negative and call names, how's Australia treating you buddy, I was thinking of moving and Australia came up, I see a lot of desert though and it's only getting bigger, what do you say?

JOES05tl

wiz is a dumbass- engine dyno will tell you crank hp. Chassis dyno's are all wheel hp. Dynapak tells you bhp, from the rotor. Comptech gives 40-60 @ the wheels as the rating for their sc, not 40-60 @ the crank, bro. I dyno'd on dynapak @ church's auto & put down 274.1 hp. Im sure that sc would put me over 309. Factor in the wheels @ 3-5% loss, Im sure it will still be over 309. I was the first! I was the first! I was the first!!!! Good-

wow. this debate is still on. you would think that after 3-4 years this has been settled already.

Bky said he had over 300HP at the wheel.
The factor is more then 3-5%.

I had a 2004 Acura TL and the HP was 258 from Honda and when adding the SC, CAI, CB exhaust my power figures can to 300 something.
When you convert it to the wheel is was much less.

Now I have a older car here in Oz, a 96 Skyline GTST S2 making 261RWKW at 14PSI. Which is 356HP at the wheels.

That is all I was saying.

Peace and love in car land.

Tuner for life...
Or atleast til my wife begins to get mad!!!

I offloaded all the dynos from COMPTECH's site before things got goofy with them...

COMPTECH's own dyno shows 288 whp for Gen 3 TL AT, and I believe that reflects both the CAI that comes with the SC kit along with their exhaust. They also state even more HP from the MT (of course). Based upon scaling the losses through the torque converter / tranny for various Honda/Acuras, my math shows ~ 325 or so HP at the flywheel for the modified TL AT configuration. And of course, adding pulleys, and Thermoblock spacers will nudge it up even more.

Hey FYI when modding vtec motors, while driving/ or on the dyno if you feel or see a noticible vtec crossover point from your butt or see it on the dyno sheet, that actually indicates not having the best tune at the moment. The less vtec engagment you feel the smoother the power band will be and the more power your will be making at vtec cross over point.

Find a dyno with a huge dip where vtec kicks in.
Then find a dyno where you could hardly see where it kicks in.. and you will actually see the power difference at that point.

DONT GET ME WRONG I love the feel and sound / anticipation of vtec, but if your looking for a good tune. You shouldnt be feeling it.

dragonlord

Got a new toy- here is my dyno sheet. I have AEM CAI and Magnaflow exhaust.

FiveLiterCheater

Was this just for the exhaust?

dragonlord

Was with AEM CAI and Magnaflow exhaust.

FiveLiterCheater

Right, but was one baseline and one after BOTH mods or just one?

dragonlord

NOPE! Both runs done with the AEM and the Magnaflow. Just about 15 minutes apart. The first run, the engine was cold. Second run was done about 5-8 minutes after the first. Weather was about 70, no humidity. Look at the times between the runs- about 14 minutes.

FiveLiterCheater

Damn, seems kind of low =( The dyno sheet on the first page seems higher than everything i've seen...Does anyone else have a dyno sheet w/ CAI and Comptech catback (5AT)

dragonlord

Not trying to say I've got the most power, I just wanted to see what my Queen will say when the loud pedal goes down. If I wanted to brag on HP, I'd buy the S/C and then spray it, and you all would cry. My Magnaflow exhaust is just a LARGE resonator, no mid-muffler and regular Magnaflow mufflers.

I'll dyno the car again with the new exhaust in the spring.

Pretty good Actros, thats without the exhaust? Did you notice any difference with the spacers?

Still looking for a decent 5AT dyno with intake and exhaust...

ACTROS

iTrader: (7)

^ Yes, stock exhaust. These parts I couldn't sell and they actually came from my previous car. I had everything installed @ the same time so I can't speak for the spacers alone but they suppose to keep the manifold and throttle temps low thus increasing/prolonging the timing---power. I must say that collectively these simple changes greatly increased the output and feel, more so than on a 5AT car.

Come to think of it this car's actually has the same output as my 04 5AT which had all the toys like Eshift cats, CT exhaust, UR Pulley, CAI, Spacers, etc... That car was tested on a DynoJet roller putting down about 240hp/215tq, but that dyno tends to read higher in comparison to this one though.

Take a dyno reading w/ a grain of salt but there's no arguing that the 6MT car is significantly stronger in all states of tune whether it's stock or tricked out. Regardless of the power, the car feels like a different beast altogether!

ACTROS

iTrader: (7)

Haha, this dude( Nitrotiger) is long gone out of the TL world...sold his TL and now drives the EVO, well at least he did the last time I saw him.

His numbers came off a Dynojet, the same roller I used w/ my 04TL. As far as I recall, at the time his only mod was a K&N drop-in filter lol

FiveLiterCheater

Yeah, I can imagine, which is why my main focus is show rather than go. 240 wheel still isn't bad for a fully bolted auto though....and with the new j-pipe thats coming out, it would be closer to 250 which is kind of where I want to be. I think i'm still going to get the high-flow cats, J-pipe and P2R spacer just to be on level. I mean even with the Comptech exhaust, I feel a pretty nice gain over stock up top.

BLKURA

Did you guys notice an increase/decrease in mileage after installing CAI?

I'm considering installing a CAI but have two concerns...first is loss in gas mileage and the install it's self. I saw a vid showing the where you had to remove the bumper!?

It takes 10 minutes to remove the bumper; piece of cake.
