I need a new Y-Pipe. Sound, Performance and proper fitment are all concerns. I have UT-R Resonated Test Pipes (2.5" out? I think) and NISMO Mid Pipe (3.0" in). I have a full NISMO Exhaust but am told that I can not get the Y-Pipe (2.5" in/3.0" out) seperately. I was considering JIC and saw one site that said it fits perfectly with the NISMO mid pipe(3.0" in), but then another site said the spec for JIC was 2.36" in and 3.15" out and NISMO is 2.5" in and 3.0" out so now I dont know what to think other than large into small(2.5" feed into 2.36" then 3.15" feed into 3.0")means RASP, but Im not sure if that will in turn yield more desireable gains, HELP! Reccomendations please

 

 

No input ? does anyone here have the JIC Y-Pipe and if so could you just give me your impressions on sound and performance?

Here you go!

 

i really like my fuji

you should make sure you take into consideration headers, cats and cat back so that you can match up your inlet and outlet diameters

 

That was originally the whole point of this thread but nobody responded to my fittment questions so I figured I would simplify it by just asking for impressions from owners.

I have DC Sports SS headers, UT-R resonated test pipes and the rest is NISMO untill I change the Y-Pipe. Ideally I need a 2.5 inlet and a 3.0 outlet but I see the JIC is a little smaller inlet (2.36) and a little larger outlet (3.15) but am told that it fits the NISMO mid pipe perfectly (3.0 in) this is where I am confused.

 

what i ended up doing was calling the vendor and asking what the diameters were of each...so you might just go directly to the source for info.
