The best advice I can give you is to try YouTube. I had a flowmaster 40 that I swapped out for my old stock muffler.

I've tried the youtube option and could not find any good sound clips of anything with headers. I am contemplating going back to a stock muffler if i cannot find anything as this drone is extremely irritating in that rpm range and i will be pulling an RV almost 500mi.le.s with it. The current muffler sounds great at idle or WOT, it's just the mud range rpm's where it is an issue

I did some research over the weekend and got some very differing opinions on which way to go as far as chambered or straight-thru and then today I spoke with a Tech at Flowmaster and he has me real unsure of what to do after he told me that changing out the muffler may or may not fix my problem and i hate to throw away money. I did install a Holley Performance Red Hot over the weekend and all it really did was quite the exhaust down with no reduction in the Drone. I have also read other things about custom tuning making a difference on the DRONE sound as well. Any thoughts on that, as i am currently awaiting a Custom 87 Tow calibration from Bill and the team.
