hey guys im thinking of getting some test pipes since my catalytic converters were scrapped in a accident and i dont need to get them replaced because they have very minor scratches but the insurance adjuster gave me money to replace them anyhow so ill just use that money to get some test pipes. What test pipes would you guys prefer because ive heard of them cracking and having other issues i have a nismo exhaust by the way. Will i see good gains from this mod with my other modifications that i have so far jwt popcharger, nismo exhaust, 5/16 spacer, im thinking test pipes would be a good mod to compliment my other modifications so far. Will adding these test pipes on a untuned z really mess up my air fuel ratio's or anything like that. I plan on going turbo in the future so im trying to get mods that are adaptable with my turbo setup other than the popcharger eveything will be adaptable im i correct on this. Thanks guys in advance for you opinions some of these questions might seem dumb to you but id rather ask a dumb question then get into something i have now knowledge about.

 

get high flow cats instead and no CEL issues. i'm sure you got after market y-pipes.

 

Test pipes are a popular performance mod. Plenty of recommendations in the exhaust forum.

 

Just Get Testpipes And Get Non Foulers And Call It A Day 10rwhp+

 

Ultimate racing HFC for the win!!

Testpipes are not my liking. The rasp and nastly fumes are too much!

 

what is the difference between test pipes and the utimate racing hfc any difference in power and where can i get his part.

 

test pipes = raspy

hfc = not so much

 

That's why I love them.

 

where can i buy these for a good price any ideas

 

Go for some Stillens, love mine. Great sound and performance.

 

can someone let me know where to get these high flow cats i wont something that gives good gains but not alot of rasp.

 

testpipes suck...had helix tp and i hated like them....very raspy and rattle like hellllll

 

so is there any test pipes that arent raspy and have good gains in power and where to get them from.

 

there are resonated test pipes

 

Ive had resonated and non-resonated. Makes no difference. Its the exhaust that makes the difference. An X pipe will reduce rasp by 90%. HFC have little rasp, but it'll always be there. Currently I have 2.5'' test pipes on a 2.5'' dual exhaust with an X pipe, and I have minimal rasp (maybe even none..) I can hear a little bit when its cold around 3000 rpm, but it quickly goes away and becomes a howling sound.

 

So all test pipes suck because your Helix pipes sucked?

 

Test pipes don't rasp as much as some people would leave you to believe.

I'm picking up some Labree test pipes with a Nismo exhaust soon, so I'll post once I have an opinion after having them on.

 

get test pipes and the non foulers and u wont regret it

 

ok cool well i want to go with some test pipes with non-foulers what website sells these products please. One more question can you past inspection with test pipes with the non-foulers i live her in texas so inspection isnt as bad as other states.

 

What about test pipes with stock exhaust setup???
