Well just thought I would throw up some back to back testing from a vt Calais full weight running a hurricane exhaust system 1 5/8 primary into 3" collector and dual 2 1/2 in an auto saw consistant 14.7 all night with exception of a high 14.6 towards the end.....unfortunately the exhaust made close to no difference
After a tune and cheap alloy otr saw car run a 13.5 best
and all this tune was with oztrack street tune for measly $500 apart from diff gears I think this is one of the best bang for buck mods for your LSX motor....
my friend should be running car also wed hoping to have 3.7 diff gears in to see what this nets
