Sound of a DP w/out CatBack exhaust

I already have a TXS UP on my car and want to get a DP but don't have enough money to afford a catback also right now. Will the DP without the catback system sound much different than stock?

The sound will be the same, just louder. If you are looking to get a TXS downpipe you are going to have to buy a catback adapter since TXS doesn't run the same exhaust path as everyone else.

+1 to wrxtreme.. its got a bit more throaty sound/louder sound but the catback absorbs a lot of the rumble with the muffler and resognator making it have a louder stock sound.

keep it in the dirt.

With no cats you get good turbo spool up and wind down noises compared to stock. Sounds really good but stays quiet ever all.... I love my QTP downpipe with the electric cutout valve coupled with the stock cat back


WRX at 218 WHP (dynapack, aprx 275 BHP) and EVO at 375 WHP (Mustang dyno, aprx 510 BHP) on pump gas.

If you are on a budget you could spring for the ebay exhaust system. It think it's around $300 or so and includes an UP/DP and catback. Since you already have an UP you could just sell the UP that is included with the ebay package and recoup a few bucks. Several people on here have installed the system and have been happy with it so far. Click on the link below for the thread.
