I've searched and searched and still can't find with exhasut gives the best HP gains. I've heard of the Blitz NUR-spec and the Apexi dual and single setups, but no one ever has dyno sheets. Does anyone know what will be the best perofrming?

 

im a huge fan of the blitz n1 a buddy of mine has it on his s13, rocks some socks man

 

the newest turbo magazine has a comparison of 11 cat back systems on a TT supra. one of them adds like 30 hp. i can't remember which, it was some company i've never heard of. anyone know?

 

wow a 30hp gain wit just a catback ive only heard of a 17hp gain..

 

you're only going to see those kind of numbers if you're turbo

 

Only See those #'s On systems that are Tuned SPECIFICALLY for the Complete Engine setup and Chasis specific.
So, most likely, that Exhaust on a 240 OR even a Skyline will be different #'s. Then, we have to throw in, Street Legal db's...

 

I just put my 85mm HKS Hipower Catback and its a VERY noticable differance. Its also pretty quiet. Im thinking i picked up atleast 20hp. I know it sounds weird, but I have a 3" downpipe, 3" test pipe and I had stock catback. But now its great. My turbo spools nice and quick..beautiful thing that I can still hear my turbo spool

 

dontcha love that!?
