Ditching the rear mufflers would be interesting. They appear to be a bit restrictive.

Yeah same size piping i put.. When i get my mufflers swapped out ill put a beore and after video up

I remember reading someone say that the kizashi sounds like a wrx if you delete the rear mufflers.

Sorry I haven't been on as much to help but if you delete rear mufflers yes it will sound like a wrx if u leave the resignator in. How ever I'm currently runing a custom 2.5 in custom cat back/ straight pipe system and it awakens the beast that this car is. In 6th @80mph there's a drone but it's not that bad the Rockford cancels it or just good conversation as it's not that loud unless Ur really on it. I've had a flowmaster on it before and it kept same tone but with less popping. No error codes and the car loves it. The noise it makes is unique and is a cross between evo and wrx to be honest. This month I'm getting stage2 turbo from rrm running 12psi so we shall see how it sounds then after the new manifold and 2.5 in down pipe are in

It's good for 290 whp supposedly but I'm doing stage 2 which is same set up just with more boost only 3-4 lbs more. I want to try to get 330whp and the restrict or deleted. Rrm doesn't "flash" ecu they just refine it to get best of the turbo app but don't touch restrictor . My goal is to be sti killer from a roll I already keep up but I want to beat them. When their limit it 155 and mine 130 u do the math lmao :drive:

Don't RRM use a piggy back ECU? It would be nice if there was a company that could reflash the ECU and do it "properly".
