HKS or GREDDY turbo exaust

greddy is supposedly making one. no word on the hks. however if you're fine with 2.5" piping, you can get hks's axleback exhaust for the p5 and just have it lengthened a bit. otherwise go custom.
 
is greddy's exhaust = all street legal? like shouldnt get pull over by cops complaining bout too loud exhaust?
 
I spoke w/ one of the reps from HKS @ the D1 Drift event. He said that they are in "development stages" of a cat back system for the Mazdaspeed.
 
Spool and I believe Ion both make turbo back systems with Spool using an HKS Hi Power exhaust.
 
Greddy Exhaust System should be out late Sept... and for the sound of the exhaust... It's legal... It's just depend on the cop, if he's anal about it...
 
Thanks for the info. I live in South Carolina and our cops are not that picky about exaust sound. Hell we dont even have to have our cars inspected anymore. So that means we can tune to our hearts desire.
 
i dont know, but they're getting lax around here, 4 year inspection periods? u could get away with no cats for a pretty long time now!
 
My friend in his 03' wrx got an greddy evo catback, sounds great. I mean you can tell its aftermarket by looking at it (oh really i didn't know the huge GREDDY logo gave that away) but its reeeeeaaalll quiet. It seems to be loudest at idle and you cant tell its on there without looking at it. I hope it sounds the same way on our cars I would love it to be like his.
 
it should sound about the same cause the turbo does muffle the sound of an exhaust alot but then again the Scooby engine sounds different cause of its Flat4 design. i happen to have the Greddy Evo exhaust on my civic si and it sounds nice low deep and bassy and is quiet when just cruising at normal speeds, so i recommend it. ive also heard this exhaust on a P5 and it was the same.
 
nothing sounds like a flat 4. just listen to hks's exhaust on their wrx compared to their others.....nothing similiar about it.
 
I cant wait to see pics of Ion's and Spoolin's completed exhausts. Thats my next upgrade but I hate buying things when I don't know how they will look. I wanna see how far it sticks out, how it look from behind, etc. No offence Kenetix, but I couldnt put an exhaust on that stuck out as far as yours :) Hope some people start getting there stuff done soon, I got money to spend!
