Test Pipe Or High Flow Cat

I forget where I saw it, but a company that makes a hi-flow cat tested this out on the same car with the same mods. They just replaced the stock cat with a hf cat, then with a test pipe, and dyno'd it. the test pipe beat the hi-flow cat out by one horsepower. I am also looking at getting a test pipe, but I cannot find anyone to put one in down here. Sigh.

 

it sounds better with the cat

 

I don't think so. But that's your opinion. A friend of mine has a 240 3" pipe from downpipe back. sounds so good. And loud. That's what I like. I love the loudness of exhausts.

 

i meant sounds good as in quiet.

 

And I think that sounding good is loud and deep tone. 2 different ideas of good.

 

gee ok cool! glad we straigtened that out

 

^LOL. anyways, the testpipe does have a bigger increase in power than a high flot cat does. it also makes your car louder. aaaand for the guy who cant find a place to get it installed, its pretty easy. theres a thread on evolutionm.net which does a great job. for like 80 bucks or whatever it is, its a great mod. just keep a legal cat lying around somewhere just in case, and hope you dont get more exhaust tickets haha.

 

really ur gonna pollute the air that much more for 1hp?
just get a hf cat and be air friendly

 

yyyyep lol

 

Also, the hf cat DOES make your car louder, but just not as loud as a straight pipe would. And even if I do get either of these (looking at buying a Talon TSi, so I may stop modification to the Lance to a certain extent) I would probably getting the hf. OBX has one on ebay for $45. And it's bolt-on, and it's legal. A lot of muffler shops like to cut the cat out fully, and just put a pipe over header and exhaust and clamp it...... But, it's whatever you want to do.
