2004 Exhaust Modification

Marty · 12-23-2006, 10:29 PM

I have a 2004 TSX and am looking into options that will economically decrease exhaust backflow. Has anyone simply removed the mufflers and run straight pipes with tips from the resinators. If so will this effect the performance and how loud will this get?

Why not get yourself Headers, RT Cat, and Cat back....

Or screw the Cat and go with a test pipe

welcome to the club Marty

i've gone with this set up: injen cai, comptech header, rt cat, greddy evo and LOVE the results

or you can do what acurasrule said and go with a test pipe but i'd have a feeling that it'd be stupid loud

dunno where you're located...but in souther cali, don't think you could get away with the test pipe with that setup. loud imports get lots of police attention....but for some reason rip roaring vette's, mustangs, camaros, and harleys are not bothered.

I ended up removing the mufflers, running a straight pipe with chrome tips from the point right before the mufflers were removed. To be honest my TSX sounds AWESOME! The catalytic converter and both resinators remain unchanged. I had a custom muffler shop do the work for $140.00.

Are the resonators in the pipes? or were they those big containers?

Like running a highflow cat and after market fujitsubo exhaust should have taken out the resonators in the stock exhaust.

They were like this i think

The two big things I was told were the resinators. My exhaust is exactly like the system you depict except that the mufflers were cut off and straight pipes with tips added. I noted in your bio that you have a magna flow cat. The exhaust professional I went to is a magnaflow dealer and they do not have a syatem for the TSX? How did you do yours?

I did record what the exhaust system sounds like in a .wav file however this forum does not support that file extention. I would like to post if anyone knows how I can convert this to a supported file extention.

I have fujitsubo exhaust but a magnaflow high flow cat.

It was done at the muffler shop in buffalo, during my school year.

Thanks Marty for the sound clip! Sounds great!

The way I look at it, I want maximum bang for the buck. If you can replace the mufflers with something better, that's probably going to give you a lot of bang for the buck. I'll just say that unless you have some serious mods, I doubt that enlarging the pipes or going with a high-flow cat is going to do much good; I think the one dyno I've seen for the cat mode only showed something like a 2 or 3 hp improvement? That's probably >$100 per HP, and probably on a car that has a lot of other mods. Much cheaper to replace the mufflers and the header. (Or even Hondata, going with bang-for-the-buck?)

Also, I'd leave the resonators in. I'd question whether they would be worth removing (they should just be straight-through designs), and they'll reduce the droning while crusing, as far as I know.

I went through all of this on my previous car. Some of the aftermarket kits have small resonators, and the noise was horrible on one that I rode in. I bought the "quietest" that I could find (which was still a bit louder than stock, but mostly when you got on it), but at crusing speeds, it was pretty decent. It had a good-sized resonator.

So, in short, I think if I wanted to change the exhaust for my TSX, I'd probably do the header, and maybe just replace the mufflers, and that's probably it. Although, right now, I don't have the bug to mod much, and this is all kind of my guesswork, so take that for what it's worth.
