Not to Hijack the thread, but I've had awesome luck with Aero Turbine mufflers, they sound good and I've noticed improvement on the butt dyno everytime... They seem to flow reallly good.. Just a thought!!

Here is a link if you guys never heard of them:

I have heard of the aero turbine mufflers, and everyone seems to like them. The only problem I have with them is $$$$$. I can get a donaldson local and about 1/2 price from that one.

Justin, thanks for the feed back, i'm still going to have to search for one that will flow enough yet still fit.

Thanks, Aaron
