Inline 6 got me wondering, why not make a custom exhaust manifold with an unequal length runner, see what kind of sounds I can get. I found the Dorman brand manifold to replace my cracked factory piece. I figure I'll just chop the collector off and run the first bank 2 foot of tube and the second bank 3.5 feet before merging. Lmk what you think. Just looking for a little more rumble sound.

Could anyone answer for me if this head flange pattern would work on an 05?
