gutted stock up-pipe. Wrapped Randomtech bellmouth DP with catted mid-pipe, and a Helix catback. a crappy video at WOT http://www.youtube.com/watch?v=gFn4am-23MA
ported and smoothed stock manifolds and crossover, TXS cast up, Bosal catless divorced down and mid, SPT 3" cat back
Exhaust on the RS is stock for now, but here's what I've done in the past: My STi had a TurboXS Stealthback, then a Helix DP/Ansa catback, then a Maddad midpipe and Afterburner Vortex axleback (with the Helix DP)..... Ansa was LOUD :bigthumb: Vortex is like a loud ScoobySport, love it My WRX's had ScoobySport components and then a full Helix TBE..... Still haven't figured out what to do with the RS yet.....
MadDad Equal Length Headers, Maddad 3 bolt uppipe with atmospheric dump Tial 44mm EWG, ERZ downpipe, Greddy Evo2 Catback with resonator removed and replace with 3" piping. Screams like a banshee.
Stromung ceramic coated shorty divorced WG DP, Stromung catted mid, STI axle back. Oh yes, also an STI catless up pipe.
stock up-pipe w/ cat stock dp w/ cats STI exhaust Catback overall: stock 04' XT *(reserves the right to EDIT)*
Was running a Brullen catback but got tired of the drone. Backed off to an STi catback bolted up with a MS3 adapter (rotated flange and pipe extend/expand). Quite a bit quieter but still makes a nice rumble and flows great. Sent from my LS670 using Tapatalk
JDM up-pipe (no cats) COBB catted down-pipe COBB mid-pipe with 3" flange rotated and an extra 1/4" of 3" pipe added to fit axleback Perrin double tip axleback
rotated 3" 2 resonators that say cat on them with an APS gutted can. sounds like a couple of carpenter bees fucking in a milk jug
Invidia Race Header, AMS\TopSpeed Rotated Piping, AMS Exhaust. All Ceramic Coated. Deep and awesome is the best way to describe it.
Invidia divorced catless, 3in to 2.5in adapter, SPT catback. Fairly quiet but still has enough rumble for me, pretty sure the maddad whisper and borla hush is quieter tho.
MadDad V2 Downpipe (catted, divorced), MadDad Whisper V3. I have about 4k miles on the exhaust and love it. Nice rumble, deep exhaust note, tame until ~3k, ~3k+ it opens up and sounds awesome.
