Also should I smell any fumes under load anytime or no?
Shouldn't have any fumes with the primaries still on there, if you smell anything it might be for a couple hundred miles after gutting the secondaries its probably burning up whatever is left in there now that the ceramic core is out. Funny thing after installing the Dinan x pipe i also felt a little more low end torque but i did have the stock non comp resonator on there.


This is my sound before the secondaries were modified and straight pipe instead of X. Sound was more raw I think which I kind a miss now. I'll post the video with new setup soon but truly miss the rawness of straight set up.

So this is just secondaries deleted with straight pipe?[/QUOTE]
This was just straight pipe and middle balance tube connecting both mufflers deleted. I ended up with Remus straight pipe exhaust, and Keller upper and lower catless.
