This is a discussion on Exhaust Video/Sound Clips within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; QTP downpipe w/cutout closed + STi Genome Axle Back Dyno run w/cutout wiiiide open....
i know its a long shot, but im looking for a few clips.
-ERZ up/down w/ Greddy EVO 2 catback
-ERZ up/down w/ Skunk2 catback
-ERZ up/down w/ any other catback
2000 Laser Red Ford Mustang GT 5 speed
gears, suspension, brakes, bolt-ons
email@example.com w/ a 2.0 60' (mods were gears and X-pipe on street radials w/ a STOCK suspension)
FOR SALE OR TRADE!
I dont think it going to matter much on the Dp/Up mixture differant size opennings on the downpie problably.
Just wanted to say one more time completly catless the Evo2 not that quiet at all for those looking for the only popular two pipes theyve heard evo2/borla. Burshur is about the exact same that i know of.

mine sounded alot better with the cats in place. a lot deeper tone. catless it seems more raspy, but hella more louder.Originally Posted by TurnWRX

So in other words, you could have a helix catless dp with a greddy catback, and then change the dp to a Perrin catless dp, but still retain the Greddy catback; there will be no noticeable difference in the sound quality.
