DAZVR6 0 Posted March 1, 2008 Report Share Posted March 1, 2008 Currently got a 6 branch manifold, decat with a 2 box system, but its a little to quite for me, if i were to remove the middle box it would obviously be louder and let off more of that v6 howl, but would the lack of back pressure loose me performance..? Don't wanna change the exhaust, just want abit more noise thats all Link to post Share on other sites
