Does Nismo or noncatback exhausts come with a Y pipe? I'm
asking because I've heard the Y pipe is the most restrictive part of the stock exhaust and its otherwise pretty good. What about the midpipe?

I like the stock look and sound so I'm thinking about running a Kinetix (or other) Y pipe with Crawford high flow cats and maybe DC , Crawford or Stillen headers.

Does this sound like a good setup or do I really need an aftermarket exhaust?

And what about hp gains? Has anyone dynoed the stock exhaust with Ypipe, highflows or headers?

Thx

 

Nismo exhaust does come with a y pipe.

 

Mufflers themselves do not add HP, only freeing up restrictions do that. I am adding DC SS Headers, Crawford Cats and a Y-pipe to my stock exhaust. The HP increase with a totally new system versus the y-pipe is as good, and better than most. In 30 days I will do a dyno. I,m considering doing the Gruppe Y since it costs 275 dlvrd as compared to Japtrix @ 350, and I question Kinetix doing a different design..it may be another Plenum fiasco

 

I just put in the Gruppe-s y-pipe. It is of excellent built quality and it is actually very attractive, not that anyone can see it, due to a mirror like polished SS finish. I bought it along with a fujitsubo exhaust so I got a discount beyond the already low price of $275. So keep that in mind whne you order. They should be able to give you a break. Just make sure you tell them you heard of them here, that will help with the pricing.

 

I agree the muffler doesn't do anything but the y-pipe and straight pipe do, unfortunately only one company sells a straight pipe without having to by the full system and that is Japtrix who also sells a y-pipe.

 

Thankyou all for the help.

Westpack, do you know where I can buy the Japtrix Y and Mid pipe? That sounds like a good deal for good gains.

I think I'll go for DC headers also. They probably get as good a gain as any other for a decent price. Does anybody know where to get a good price on the DCs? Also, is the fitament good? I've heard less expensive headers somtimes have a problem with this.

Japtrix+Crawford+DC should equal some really good gains!!

 

Yes, you get the performance benefits for a fraction of the cost. They are here in Florida and you can contact them at 561-963-8700 and ask for Roger Acham or Roger Case, really cool guys.
