I currently have a Folger can (haha) for an exhaust. I want to know if I get any advantages with a Flowmaster catback or other similar exhaust systems. I love the flowmaster on my 350's (mostly for tone) but this is different.

I would like to hear any opinions on this and any web links for exhausts.

 

Roffles. The ricer's mods. Coffee can. BTW how wide is it?

Anyways, I would go on YouTube and just look around to see the exhaust notes.

 

I've got just a general question. Do you have to get a high flow cat in order to have an after market muffler. My goal on my car is to make it sounds louder (and cool, no stereotypical civic sounding crap). I'm just wondering what all I'll need. I was hoping not to have to buy a high flow cat because those are really expensive. I know I probably won't get any horsepower gain by going with just an aftermarket exhaust and no high flow cat, but I guess what I'm really going for is the sound. Some one told me you only need the high flow if you plan on putting turbo on the car. Which I don't plan on doing (it's an automatic).
Question: Do I need a high flow cat for an after market exhaust?

 

if your going for the flowmaster sound, try imco pro muffler. There's alot less raspy and a deeper hollow tone with out the tin can sound.

I have a high flow cat, with a 14 inc res,and a imco extream, and a dynomax super turbo at the end.

its has a odd tone to it, but its not bad tho im planing to go with the imco pro this summer tho.

""high flow cat will add sound and more rasp, thats why i got 2 muffs and 1 res.

 

I know this is kind of a noob question, but what is the difference between the high flow and regular cats? Could I just buy like an ebay high flow cat? Would it essentially do the same thing as shoveling $300 out of my bank account?

 

Most eBay "high flow cats" or nothing but a resonator or straight pipe. They are not catalytic converters at all.

A high-flow cat is different from a standard cat because the internals is constructed of different material and in different shapes and formations. A good high-flow cat will have more air flow with little to no more emissions.

 

a lot of high-flow cats are basically the cat of a larger vehicle with flanges to fit your exhaust (which won't actually help your performance)...however, philadd is correct that some high end high flow cats are actually designed with improved internal construction to flow better...

as for exhaust....i'm currently running my h22a with the kteller stainless exhaust (2.5 all the way back) with two magnaflow straight through mufflers; one muffler in the regular position and one about where the cat used to be...i'm running a removable test pipe right now that I can interchange with my cat rather conveniently...with the mugen header, it's nice and deep and very little rasp...even at wot, the sound is just loud, not raspy...there is very little restriction in the exhaust and the power gain is great up high...h22's love to breathe up high...

 

so the ebay cats really aren't cats at all. Just a pipe that goes in between the exhaust and engine? Some have an O2 sensor does that make a difference?

 

If you want both good sound and performance, you might need to spend a little money...

Personally I would go with the RS*R Exmag system...its a little pricy, but the quality, tuned exhaust sound, and performance is great; that system is specifically engineered for daily driving (read increased mid range power)...unlike other "Performance" exhaust systems which take away a tuned and subtle exhaust note in order to get the most high end power.

Its also best you have a good high flow catalytic converter.

Otherwise the high flow exhaust system will not be used to its potential.

 

I just bought an Apexi-WS2 got it at a fairly reasonable price and it sounds amazing!
Quiet enough not to catch the attention of pork and doesnt have that sound you would normally get with a fart can. Might i add, It looks flippin' good too!

here's one on a 5th gen. ^^^

 

Got any pics of that?

 

Is there anything bad that could come of running a test pipe for an extended period of time, like for the summer or something? Like back pressure issues, I don't want to be bending valves!

 

If you run a test pipe, you will have less back pressure. This will do several things, if everything else on your car remains the same:

1) Your engine will run more free at higher rpm's, and put less pressure on the engine.
2) Your exhaust system will become louder.
3) Your low end torque will decrease, due to less back pressure.
4) Highway mileage might rise, while stop & go traffic mileage will drop.

So...putting a test pipe is great for highway driving or even road racing, but at the cost of low-end torque, driveability, and longterm comfort.

if you get a test pipe, install a high flowing intake system (SRI or CAI).

 

What's up lokuputha!! Coming to the dark side I see..lol...Back to the exhaust question, I would recomment a hi-flow cat and a free flowing exhaust like the R-sr or WS2. Or you can go to a local tuner or garage and see if they can build you an exhaust mandrel bent, it might be cheaper than the brand names, but it will still work effectively

 

Thanks for the advice, that helps a lot!
