Hey guys I'm looking to purchase a catback exhaust but finding it pretty hard, wanted to go with atlp but theyre waiting on more demand for the next production so itll take awhile, any advice on where to look or anybody selling theres?

FishiRox

go to k2motor.com and buy a spec-d exhaust catback

BigHatch

Nobody makes anything anymore.

smk31684

fishirox- which spec d catback in particular and do you have one and hows it sound?

Mr Marco

I'm sure you could get a custom job at any good shop with the proper materials and equip (BendPak 302 & 2-1/2" tubing).

kidfury

how much $ roughly?

Mr Marco

Last cat back exhaust I had done on a 4 banger was on the Speed6. It was $290* (3") with muffler AND tip! I thought it was really reasonable. If you were to buy the CP-e SS system for the Speed6 it is now $690.

*that was in 2003

smk31684

just placed an order for the atlp cat back a few days ago, hopefully theyll get a few more orders and can get them made because im excited

wspy

^ They need 10 orders to make that happen!

BigHatch

Let us know what they say...if they hold onto your $ or return it. I think they may be not to far from here, in South OC??? I should check. or heel toe anyways.. one of them was, i forget

smk31684

yea i havent heard anything this week from them but ill keep you updated. yea im not too familiar with anything in orange county being all the way over here in florida i just know heel to toe is in California

For cat-back, I recommend getting your choice of muffler (I bought Magnaflow 12267 from Amazon, free shipping) then taking it to your local muffler shop to install it using mandrel bends. The stock system has mandrel bends so it'd be a waste if you're going to use crushed bends.

You can have them install a cat-back or axle-back for about $150-400 with your choice of tips. Much cheaper than purchasing a full exhaust system and having it shipped.

DRR98

Thanks IJ, thats a much cheaper way to go. I could delete the b pipe and swap in a magna flow, and run the stock tips.

How much did you pay for the muffler shipped?
(they add sales tax now, sniff)

Do you have a sound clip of yours on the car?

Is it loud or droneish at cruising speed? TIA

smk31684

I talked to atlp yesterday and he said he was working really hard to get orders..soo if anybody really wants a cat back you should check atlp out

Ops is looking for something that doesn't cost over $1100.
Normally if you buy the parts - it would be around $400-600 max to have a exhaust shop custom make one including part and labor.

Might not be as nice as the ATLP one but for more than half the price.
It doesn't seem to bad of a deal if you have the time and patience to research a little between the parts needed and a good exhaust shop.

JCRDX11

I meant DRR98 was looking something that doesn't cost over $1100.

bmeyer99

Would this kit work?

no mufflers though

InfamousJamous

Shipping was free on Amazon! I have not been charged sales tax on Amz (shipped to CA).

No sound clips at the moment.

Not dronish if you have a resonator. You will get drone without a resonator so keep the stock one, or get a Vibrant Ultra Quiet Resonator if you delete the B pipe. No need to delete the B pipe if you don't plan on sticking to 2.25" though. Most people just need an axle-back.

So what is a good size to go for the b pipe? Thanks

InfamousJamous

For street you can stick with 2.25" or upgrade to 2.5". I suggest starting with a 2.5" axleback and 2.5" B-pipe with resonator, keeping the stock flange locations so your system is modular with the stock pieces for the long run.

They say 3" is the minimum for turbo engines though. I chose 3" with extra resonators to keep the exhaust note in check.

Some good reads on exhaust systems:

So for everyday driving 2.5 inch is good then. Wont 3 inch backfire on our car?

BigHatch

no. the only reason you'd backfire is if you were VTA and extra unburnt fuel would ignite when it got out.. straight piped..

3" would be ideal... The turbo is the restriction in the system. after that you don't want any backpressure for pure efficient performance

...sound is another story

InfamousJamous

Yup, afterfire happens when removing the cat(s) too. With my catless setup, I get occasional afterfires when jumping off the throttle at high RPM shifts (usually between 1st>2nd) but not during normal driving.

If you want a more aggressive exhaust tone with some gains then just go with an axleback. It's cheap for only $200-400 installed with tips.

If you want the most power and mpg out of your RDX then you won't be happy until you go 3". I learned the hard way and kept upgrading, wasting money. Go big or go home!

Tucked in nicely!

this thread needs some videos

wspy

What was the time in the quarter?

RDXturbo07

time please i ran a 14.6 with hondata and typhoon intake

InfamousJamous

Just to clarify.. I was agreeing with BigHatch but not saying it will backfire if you go 3" piping.


I love the sound of my Magnaflow.. smooth and aggressive. The staggered wheels looks good from those angles btw.

Mods: 3" custom exhaust and Jdm password intake.

JCRDX11

We need some sound clip if possible. =)

KenB350z

Yeah, RDXturbo07 you're on Dragtimes.com

KenB350z

I will try to get a video clip with a better camera, my phone camera mic can't handle the deep tone of the exhaust.

REVTEC

Intake is sick! You said it's a PasswordJDM intake? I can't find it on their site!

KenB350z

I got it from JDM Password, they don't currently make an intake for the rdx. So I looked for the closest fitment style they had and came up with the Honda Fit JDM Dry Carbon Fiber PowerChamber Intake 07-08 Fit looked about right. With a battery relocation kit the hybrid fitment worked great!

BU

^ That's awesome idea. Intake is huge.
Where did your battery relocate to ?
in the trunk ??

KenB350z

Yeah, it's in the trunk. I will get some pics when I get a chance.
