is there any power (milage) gains with strait piping a mpbr system or is the muffler just as efficient?

IMHO, no, just sounds a bit louder.

I don't think there is any way it can be as effecient. If you already like the sound you'll probably love it cut off

It sounds alot better if you cut it out. You won't regret getting rid of the muffler:grd:

My buddy has a saying from his own prior experience with this subject (and I tend to agree w/ him) "Loud's (as in straight pipe loud) cool for about 100 miles..."

What about loud(as is open header loud)? It's not bad as long as you're in front.

I really think mine is not as loud cruising as it was with the muffler.
