I'm going to drop a Turbo built b16a into my dc4 and Its going to be my daily driver. I'm not going to boost high, something below 10 psi, but right now I have complete 3inch exhuast with a 3inch N1 muffler, and I realized that since its my daily driver, I want it to be quieter. so would what be a quiet alternative that wont restrict my exhaust flow too much? should I get smaller piping?( 2.5,2.75), buy a complete exhuast like RSR or greddy, or should I just slap a cat onto my 3inch piping and leave my silencer on?

Thanks

2.5" pipe to a Dynomax muffler..... excellent flow and a quiet purr

to a how big dnymax muffler?
so best bet for a quiet and not to restrictive turbo exhuast is to sell the piping i have now and by another huh? so slaping a cat on a 3inch exhust wont do much to quiet it?

Just slap the cat on. That will make a big difference in sound.

No need to sell your current piping.

You can run 3" with a cat but definitely lose the N1

so what are you suggesting? run the 3inch all the way through, but have it exit through a smaller more restrictive muffler?

i dont think the n1 is the kind of exhaust you would want to use if you want the car to be quiet. i would run the cat and get something like a magnaflow exhaust.

I see,I see, that magna flow, remains 3inch or minimize it to a 2.5 or 2.7?

You can find dynomax or magnaflow's in 3" inlet and outlet. Neither are very restrictive

get a 3 inch hi flow cat with a dynomax/ magnaflow muffler

i have a 3" thermal...no cat...but a large resenator

its reallly quiet (for a 3" exhaust)

if you want silent, go with an e-cutout
