I wanted to know if 2" pipes from the mufflers to rear end of the car would create a lot of back pressure and would I lose power? Also, I was think of changing the 2" pipes from the mufflers to rear end of the car and change it 3" pipes would i lose power and will the sound become more deep and loud. Any help would be greatly appreciated. thanks
I'm runnin 2" duals all the way back and It works fine. the v6 doesn't breath that much so having that little bit of back pressure helps retain power. 2.25" would give some HP but not as much as 2" and with 3" you would lose HP.
