What's a catback exhaust system (corsa, magnaflow, ect...) worth hp wise?

[ddlopes]

Does anyone know how much horsepower a catback exhaust system is worth? I recently ordered a PPE catted downpipe. So now thinking if it's worth it to order a catback.... Thanks

I know with a Livernois tune DP are roughly about 20whp and the Corsa cat back your talking about 15whp so basically when you get a tune from LMS THE TUNE HAS PARAMETERS TO SELF Adjust for cat back exhaust and CAI,BUT for DP you need a revised tune to get the most out of them,good luck.

Ok..thanks....
I also ordered the air raid cai, sct tuner, 3bar and 170 thermostat... I'm hoping to see a big improvement. I wouldn't mind a catback system. I just don't want it loud. It's my wife's car! Lol

The tune plus your goodies should get you around another 100 HP!!! The dpipes are the key to get those turbos spooling quicker, with the exaust as more of a sound thing with modest power gain per the cost. Good luck and watch out for the perma-grin , excessive driving of car may result in sore facial musscles...lol
