Right now im running a open downpipe, sounds like a tractor. Im not sure if im gonna run it under the passenger seat and dump there or just run the 3" all the way back

I was thinking about getting a muffler for it but im not sure on what to purchase, Id like to keep the exhuast somewhat free flowing, but if I do get a muffler like it to sound something like the wrx, obviously a deep rumble

eek, i started my car open downpipe when i first got it running, and it was CRAZY loud,i cant believe your driving like that, lol. Id personally go 3 inch back with a good turbo muffler, very little restriction and still somewhat bareable. Im about to ad a magnaflow resonator to my setup, because its a bit loud for my taste. At the moment i have 3 inch all the way back with 1 turbo muffler

im going 3 all the way back

i went custom made 3" bore and 3.5" tail pipe. but 3" is good to flow enough for over 450BHP (flywheel) 2.5" would be ample for around 300BHP, just make sure you get one with mandrel bends.

I think the 3'' bullet muffler is a good choice and also affordable

Yeah i have plenty of mandel bent pipe. Im thinking just pulling it all the way back, but its pretty damn expensive to go over the rear axel

thats how ive had mine made. cost £700 tho.
