Alright ladies and gentlemen, I believe this one is going to be a doosie for ya'll. Im running a stock 94 GSR with only an Injen SRI at the moment and I have decided to replace my whole exhaust system and cost is not an issue... my ears are. Its going to be as quiet as possible. So with that being said, heres what I have planned

1) I need help choosing a header...

2) Cat... Highflow or no? (Length?)

3a) ITR B-pipe with resonator
3b) custom 2.25" B-pipe with 2 resonators from a shop quoted around $150-170

4) ITR Muffler (definite choice)

3a and 4 both being bought new from the dealership. I hope to run a 2.25" exhaust through the whole system. What do you think I should run as a header, even if it be a good ol' ls or itr header just to get the length correct and keep the noise low.

Basically just tell me if you think this setup sounds nice and quiet for a DD while accruing a little gain in horses. Also, what would you suggest for a header to fit within my contraints.

Thanks
Bman

That looks like a good set-up. I would say no on the high-flow cat because that would also make it a little louder, keeping it stock will most likely keep it most quiet. Also, changing the header probably wont change all too much, id go for one that fits the rest of the set up the best, itr maybe if it fits

 

i would want mine a little louder. i plan on going with the jdm itr heard or race header rep of jdm itr. custom 2.5" bpipe no resonator and itr muffler. i think that will sound good

 

since im running the stock cat and header from a gsr, I would have to replace the header AND cat to something that fits the ITR or else it would end up 4.5" short is this correct?
