i have heard only good things about this mod and i am very interested in doing myself. However, the price seems really high for replacing your cats. I know there are three of them but what is the reasoning behind the high price and is their a cheaper alterantive?

 

The reason for the high price is because supposedly they are very very high quality cats..They're from a comapany called Metal Cat i think and they are high quality. Also keep in mind that no one else has anything like this out for the TL and there is a demand for it. Its alot more work than it sounds because the guyz at e shift have to weld in the bends and make sure they bolt up to the TL. For the Gains alone that the cats show on the dyno is good enough to justify the price, especially for me, Not to mention that no CELs came up and the car just has much more pep and its a consistent gain of whp throughout the powerband. If u search theres a huge thread about the Cats, that describe the company and everything u would want to know about it. Trust me, its worth every pennny and almost everyone here will tell u the same, only the supercharged guyz saw only 12 or so whp...if theres anything else i missed someone else will jump in

i found that thread

Is it worth it? HELL YES!!! I have them and installed them myself. Not only do you get a power increase, but there is also a MPG increase. This is one of the best mods available for the car.

BTW, the cats are all stianless steel and so is the piping. These are high quality items and well worth the money.

Check these numbers out. My car makes 294.7 whp and 249 ft lbs of trq. On comptechs website on the 5AT here is their numbers AcuraDriver2006 only makes 279whp with his 5AT. So comptech must of juiced theirs up a little. But look at the trq number on mine and comptech.

So if you look at the same dyno the same day 1 hr apart. I have the procats and AcuraDriver2006 doesnt he made 279 whp and 228 trq. I made 295 whp and 249 trq. I think it is definately worth it. Thats just me. 1200 for 16whp and 21 trq is awesome for that price.

 

every car is different.. gains will vary, depending on the car.. mine for example gained only 11 hp 7 trq.. no 2 cars are the same

 

Hey you got a beast, comptech only gives the 6sp 294 whp and you were at 314 whp without the procats. I bet you like that. I would. You got to make a pass at the track with your car, I would guess 13.5's. The key to getting the best time is the first 60'. If you can get yours down to 2.0?'s your in. Shit Ill even meet you there and slap my Drag Radials on you car so you can get a good launch. We have the same rims, direct fit.

 

I am not sold on the quality of this mod. I have friends who have done this mod to other cars and then in a few years the cats break down and rattle really bad.

Not sure what kind of magic fairy dust they use to prevent this.

-Lee

 

Are they using the same cats? Because other high flow cats from places like random are total crap...they dont even last a year.

Travis

 

Recommend Highly!

 

Nope, Not the same cats....not the same company.

BUT all cats have similar parts. I assume there are similar manufacturing steps involved in making a cat as well. Not sure why these are so much better.

-Lee

 

No kidding Lee...dang man...got me thinking I should take this junk off my car now! It must be doo doo....what do you suggest man?

 

Lee, have you even seen a set of E-shift cats?? I have, I installed them myself, the quality is 100%. In all reality a cat should last 100-120k, if its a ceramic or metal cat, as long as it is of good quality.

 

well i think you guys have sold me. Once i get my next commission i think i will be picking up a set. thx for all your replies.

 

Great! If they are good quality....apparently Travis(from a few posts above) agrees that cats can be crap. He must have experienced the same thing.

I have not seen a set of Pro-cats Only helped install and remove said cats above(not a pro-cats set).

I hope they last a long time. Just sharing my experience.

Mr. Benz, no need to get bent out of shape.
-Lee

 

Not sure that is getting bent out of shape? Isnt that just taking your advise? Or what was the purpose/point? I am just considering what you have to say Lee? Its like you are not happy unless nobody believes you or something and you have something to argue about...

 

^-

 

where there's an argument, there's mr benz.. love it

 

Oh no,

 

I think that was the whole point...there really is no arguement. lol. We all know these pro cats rock ...

BTW...nice attempt to "fan the flames" where you perceived there to be an arguement.

 

Alright let's not have a :gheyfight: , let's have a :gheyhug: ROFL.. I love the smilies on this board. Just messing with ya Mike.

 

Hey Mike, hey called you ghey!!!! He said your just so sssswwwwwweeeeetttt!!




Just playin with ya.

 

 

Yes...I kind of noticed that. O'well....lol

 

QUESTION - whats the difference in installing this and just cutting out my old catalyic converter and putting in a straight pipe (besides not being street legal)???

 

^-you will have your CEL come on, it will probably sound like shit, and they will be a pain in the ass to reweld onto the car when you need your smog check

Pro cats replace the OEM cats and give you more power. Still not clear whether they are CARB compliant but it will be much easier to remove and replace to OEM when it comes time for a smog check

 

OK this is all wrong.

You will not throw a cel if you have an o2 simulator on the straight pipe. OEM cats restrict the flow of exhaust. Straight pipes free up the flow. You will get the same performance increase from running straight pipes at the cat positions.

Actually it will sound awesome and it smells just like a race car. Now the police don't like it much in cali. Not sure your state's rules......you make the call.

You may pass emissions if they just plug into your odbII port.

-Lee

 

^-Has anyone found a plug for the TL. I remember people were trying to get one to work and no one was able to find anything for the TL. I could be wrong about that, but from what I remember there is nothing. Some correct me if there is.

I never discredited any gains from having a straight pipe in place...dont give your smart ass replies to claims I never made.

I really dont think it will sound great...granted I havent done this on the 3rd gen (have you??) but on other cars it was a little too loud and needed work on other parts of the exhaust system to get a good sounding tone. This is probably more of a personal thing than anything else, but hey, if you like the race car tone, more power to you.

You will not pass emissions, that you are seriously in error on. Do you live in California? Do you have any knowledge of california emission laws? The poster that I was responding to does, and was giving him the heads up.

I understand you are an engineer or something like that, but that does not make you all high and mighty. Your replys to other peoples post are getting very annoying and you are making yourself out to be a huge ass. Other people are taking notice. I've almost started to ignore you but replies like yours give people the wrong information and I dont want others on this thread to get dumber.

Wise up and have a better approach in your posts.

 

if the pro cats are so great, like they increase power and mpg, why didnt acura make them stock? there has to be a negative.

 

It's all about the $$. They are not cheap. Another reason why Acura doesn't offer a supercharged option.

 

It is not just about the cost of the cats, as previously stated, it is also the fact that Honda wanted a Ultra low emission vehicle. These cats are good and work as a true cat would, but be high flow, they do not work as well as a catalyst as the factory ones. Manufactures are not going to be able to fully tune a car for full performance, there are trade offs that have to be made. Higher emission standards for lower MPG or HP. This is only one of millions of trade offs that co into every car.

In a perfect world a manufacture would do these types of things, just like the larger ground wire for the chassis ground on the car, they use a 8 guage wire. Yet in the tuner world we re ground the whole motor with 4 quage, the question has been asked why does the manufacture not do that to, as it helps the performance of the car. It boils down to trade offs and $$$$$.

Jason

 

No he was not wrong. You will throw a CEL if you run a test pipe. An 02 simulator fools the system into thinking the AFR is leaner than it is by locating the oxygen sensor further away from the exhaust stream. OEM cats restrict exhaust flow b/c they are trying to clean up the emissions as much as possible. And you won't necessarily get the same power. Some back pressure is needed, espeically on N/A vehicles. If you are too free flowing you will lose power if you're not boosted. And you probably won't pass emission b/c most emissions won't pass you if you a CEL on or if they visually cannot see a cat.

 

I don't know if you are familiar with the 2nd gen TL's but the Comptech headers produce 20-30 whp over stock headers. Why didn't Acura do that from the beginning? For a number of reasons probably: cost, emissions, the fact that the TL is a luxury vehicle, more power equals more pressure exerted on the rest of the vehicle's parts (tranny) ....

 

Personally, if the car came all modded up it would take all of the fun out of it for me. I like to feel the difference each mod makes.

 

and we wouldnt be able to smoke almost everyother TL out there. Especially the cool older guys at the Red lights that want to play around. Then you smoke them.

 

Easy there hodgie! Wont be long until you are among us old farts! lol! God...it is just this year that I have been reminded twice that I am there...some kid in line bumps into me and his girlfriend says....quit it X (enter name here)....your creeping that old man out! It was then I figured out they were talking about me! lol! As they stood in line all in their Abercrombie and Fitch sweatshirts and I stood there in Pre-Motorcross attire....and they call me an old man! Geez! Powder Puffs!

Anyway...ya...I love it when a kid pulls up next to me and wants to show his girlie what its all about....nothing more priceless than getting another kill at the expense of some kiddies pride!

 

I hear ya, im 29 in 2 weeks. Ouch. But I meant 60+ years of age. That was the old guy I was talking about. At least he looked it. But he was cool, he egged me on to a friendly race. Everyone knows the outcome.

 

Ah...I am just playin with ya...you know we are friends! Its all good! I know what you mean though!

 

Not quite. You will not throw a cel if you are running an O2 simulator(it has to be the right one). I have done this and did not see a cel (not done it on the TL).

The comments about the 02 simulator are all correct.

The comments on the straight pipe are sort of correct......this is all relative to the diameter of the piping for the straight pipe. The s2000's straight pipe is actually a bit smaller to provide some back pressure, larger piping sizes actually lost power compared to the cat....There were 6-9% gains with the straight pipe in that application. And gosh darn it....not a cel to be seen.

Vtec controllers are another story.....Cels all over the place.

Pressure argument only works if you are talking about purchasing a non-engineered product. Sure, If I am making a straight pipe in my garage without a dyno to test or without understanding the flow.....yes, I may lose power, but I may not if my applied math and physics are good and I strap it to a dyno.

If I am buying an engineered product and I can see an independent dyno with the results, I will not lose power.
