Sorry i posted it in the wrong forum. just wanted an answer...
I just got one put on. It was off a buddy of mines who said he blew out his flex tube. So he put solid steel in place of that and got it welded. Has anyone with test pipes and the nismo exhaust ever blown out there flex tubes? thnks

 

first all, does that combo rasp? trying to find test pipes that wont rasp with my Nismo if thats even possible...

 

I used helix test pipes. a little rasp but nothing to bad

 

My nismo exhaust ate my test pipes. The welds on the resonators broke. I was told by my friend at spl parts to make a brace for the test pipes and that the flex joints on the nismo y pipe really didnt do much.

 

if you dont want rasp dont put tps with nismo.....

 

I haven't had any problems with mine.

Nismo + APS test pipes

 

i had a hole my flex pipe coz i bottemed out, but blow it? naa

 

plus i just upgraded to a JIC y pipe, hehe i feel a lil bit of a pull lol

 

how much did that y pipe cost you?

 

yeah, but a "little rasp" is highly subjective in what that means. doyou have a sould clip (know that may not even be accurate). I just dont want to be one of those people who remove there test pipes because the rasp and smell pisses them off...

 

Hmm, Im thinking about doing this...how much did your Nismo y pipe go for?

 

how much do test pipes actually give u as far as hp. I wonder if it would surpass a hi flow cats results.Also, i wonder if i will thorugh a cel with test pipes on a revup.

 

by like 1hp...

 

lol, yea i fully dont understand the rational of the test pipes cause im still trying to see if its that much imporevment over a set of hiflow cats

 

The test pipes are much cheaper and flow better --- simple rationale to use them

Even if its only 1hp better the cost 160-220 a set vs 5-600 for good quality met hi flo cats is easy to see

 

do they throw cels in revups

 

Not with the non-fouler mod.
