Muffler on Flat Head Loop Pipe?

[spotteddawg]

Anyone ever run a muffle on a loop pipe with the flared end? If I cut a muffle at the taper so it matches the flared end of the trumpet and tack it on, will I negate the benefits of the loop pipe?

We've won a feature with a loop pipe and a muffler clamped on it. Better check about tacking it on as I don't believe you're allowed to do that; unless it's an open class or not many rules.

best check it on a Dyno... From my experience it kills the loop

personally just run a good muffled pipe . the difference is nothing that will win or lose a race for you

Does it make that much of a difference running a loop pipe than a 45° bent pipe with no muffler? Running on 1/4 mile track wide open entire time and drafting
