that's right; ROTS, not rocks!
yes, it is quite an improvement over the stock exhaust, however, THIS IS THE THIRD TIME I'VE HAD TO PULL IT OFF AND RE-CUT, RE-WELD THIS LIL' BUGGER!

seems as though the metal it's made of is of VERY POOR quality, and although the welds were plenty strong, this thing keeps disintegrating at the expansion end...
this time I've attempted to add some strength by adding a piece going into the chamber, which I hope I've cut in such a way it doesnt negate the whole purpose and function of this thing, but...?!?
anyone else experience such frustration w/these?

yea the welding is real bad.
mine is slightly off. so i could make most of my port work super smooth.
but there is this one spot that there is a lip that i can't do anything about unless i learn how to weld.
i'm happy i got it still though.
i have never even used the stock pipe.
i'm going to get one w/a silencer.
in the meanwhile i might even atach a silencer from a parts store.

i would be SOL if it broke on me since i can't weld.
i'm trying to change that.
