I have 2 questions then.
1) If you install just the muffler on a pre-07 mada will you see any power gains worth while of the muffler swap? Will the power gains be similar to the post-07 models?
2) Does it make sense for the pre-07s to convert to the new set-up and will they experience any power gains just by doing the swap? Or does it make sense just to build one from scratch?
So when you buy the aftermarket catback system from any of those companies you listed the tubing will be bigger from the Y-Pipe to the tip?
I thought I read on the Titan forum that going bigger diameter on the tubes was bad.
It all depends how big you go. because if you go 3" you could lose back pressure and then you lose HP.
