Hi guys, I just recently installed a rmr dp and tp on the car, but kept the stock exhaust. I also installed a cone filter and a mbc and i have noticed that my low end torque was gone. I was wondering if adding a cat-back would help. I really don't care about the low end because at the top end it pulls like mother #$(@*# =). But i just want to save gas and not step on it too much since our gas prices have been so high.

 

Of course an exhuast will help, I mean it just makes the air flow even smoother. Look into an RsR or maybe some other high flow exhuast.

 

I think it might be the 3" downpipe that contibuted to losing low end. A catback will help.

This is the issue i faced when I had to pick between the 3" RMR DP and the 2.5" or 2.75" HKS DP. I picked the smaller of the two and didn't lose much in the low end. Supporting mods will help bring it back.

 

Thanx guys. I am looking at the turbo xs cat-back to finish off my system. Hope that would help.

 

cop that turbo xs catback.that would be sweet.
