I believe most up pipes are the same diameter as stock(minus the cat), downpipes range from Turbo-xs's massive 4" pipe, to 3" or 2.5. Midpipe back are mostly 3" if you want to be really loud or 2.5" for performance gains/nice deep rumble without waking up the neighbors. I'm sure everything goes bigger by some company out there, this is just what I've seen.... "POSER MOBILE SAYS YOUR OUT'TA PRE-PAID MINUTES YO!!!!"
the random tech i'm getting is apparently a 3". I was worried since i didn't know any better that this might be too big and cause more low end torque loss?
so i'm gonna be pretty loud with a 3" full exhaust? or will still having cats quiet it down considerably?
darn.. i don't want to get a headache driving... this is my 90 minute a day beater after all... should i be rethinking this guys? I don't care how fast it is, it CANT become annoying to drive it..
Not to threadjack, buy holy crap Jason, your sig vid is like a MEG. Killed my connection at work today.
I have a full Stromung setup, 3" down, 2.5 from midpipe back and its fairly quite. Louder than stock but not loud enough to alert the authorities. I'm really happy with this set-up. So, I'd say, if sound is a factor I'd back it off to 2.5.... P.s...How are you going to have 3 cats with an aftermarket setup? 3 hi-flows?
random technologies is where i'm getting a present for me delivered. this isn't really a matter of 'shopping around' guys... I'm sure my pop has some sort of favour he's calling in on them, or something.. http://www.randomtechnology.com/subaru.html
stromung has a nice deep tone... good sound but not too loud... y don't u get the blitx nur-spec and join the dark side :evil:
maybe its me but i like the loud sound of our cars..sounds good!! hell half the time i dont even have the radio on
thats how i drive most the time also. no radio. love the growl of our motors. be one with the car. lol
hey milo I rode with you, & you're running dp and back without a cat, right? what diameters were yours?
its just u:rofl:, sorry i missed ur car at the install day, freaking work, u should try coming out to north point thursday i want to see it
i have the helix dp with one hi flow cat in it... up-pipe is catless... the catback is 3.1 inch i dont remember exact diameters of the dp but i believe its a 4 inch bell tapering down to a 3
well heck, i'll end up with more cats than milo, and if its the same as his or quieter, it should be fine...
if u are ok with the sound on mine, u can pretty much get any exhaust on the market... the helix+blitz combo is one of the loudest combinations available
i saw a big jump of sound from stock 3rd cat to stromung high flow cat. The sound is PERFECT right now. Don't wanna get any louder. my setup: catless up -> 3" catless divorced shorty dp -> 3" highflow cat -> stromung catback I consider my sound is quieter than milo's
