Best Exhaust For single turbo / without cat.
I do not want any restriction if any.
Also don't want it loud either.
Thanks for you help

 

You don't want restrictions and you don't want it to be loud..... does not compute.

 

I know but i dont want to lose hp by being too restrictive
i was thinking of
rb single tip
apexi
hks sp
pfs
i just want to avoid the wrong attention when in the city. i dont care too much when on the highway

 

Your best bet would be a resonated midpipe + a RB catback, a resonated MP doesn't add that much restriction, and is a ton quieter than a regular MP...plus its a street car so a little restriction at the expense of extreme loudness should be fine.

 

St. May's shotgun exhaust. dual canisters full flow too without being too loud. and as said before a resonated midpipe

 

Get a A`PEX-i PS Revolution with a resonated midpipe. The piping is 3" for about an inch, then goes into 3 1/4" for about 3 inches, then into 3 1/2" for about 5 inches, and from there to the canister is 3.75". Only problem is the exhaust is expensive. Hella rare though. I havent ran into anyone with the same exhaust ever...Then get a RX7store resonated midpipe.

 

look at my buddys jerome thread on the single turbo section
He has a GT35R with a full four inch exhaust and really its not too loud bc the muffler is rather long

 

+1 it only gets loud during high RPM action

 

Unless you have your smog situation worked out, then I wouldn't go crazy with a 4". If you have to pass CA smog, you'll need a CAT (restriction) and you'll want to keep the police from eyeing you everytime you drive by with decibel meters in hand (loudness).

Maybe the RB Dual Tip and a good CAT - would be best for a CA vehicle. You're gonna have to run a CAT if you want to pass CA smog.

If you don't have to pass smog, then you can widen your options to whatever you want but be prepared to eventually have to pop the hood with a California License Plate.

Jerome's setup is pretty interesting but ever 4" I've heard in person is loud as f*@k.

 

thanks everyone for the info. I am thinking of just going with a rb single with resonated midpipe or borla xr1. I hope this does not screw up my current tune.
