Probably could have picked up a little more with jetting but the bottom line was the Dynomaxs' out performed the Flow's in his swap. I think there were no other changes during his testing other than the mufflers. There was a Moparts member a few years ago that changed his Flowmasters at the track (on the same day IIRC) to Dynomax and picked up several tenths in the quarter. One surprise was the performance and sound level of the Supertrapp mufflers! Pretty much knew the Dynomax mufflers were much better all around over the Flowmasters hands down in almost all of the categories. Re: Which Flowmaster is the best applicationĭynomax super turbos on all my cars never had an issue runs good too.Ī few surprises with that article thanks for posting. ULTRA FLO™ STAINLESS STEEL POLISHED - OFFSET / CENTEREDĪnd on aside note,personally I wouldn't put a Flow Master on my John Deere,but that's just me ! Mike,illustration is wrong,description is correct.Also if tailpipes are correct they would be 2 1/4" same as B-body so that means a tail pipe change with this muffler This is one of the box labels on the mufflers I have (dimensions are on the label in inches): Part number 17289įound this just now on the Advance Auto parts site for $195.99ĭynomax Ultra Flo SS Universal Muffler part # 17289 Every other site shows it as offset in and center out both with 2-1/2" diameter.

The Dynomax official site shows it as center in and out which is incorrect. The mufflers I have are 2-1/2" offset in and 2-1/2" center out. Do you have a 2 1/2 inlet and 2 1/4 outlet? Tell me what Dynomax muffler you put on your Road Runner.
