Muffler Size Differences - The 1947 - Present Chevrolet & GMC Truck Message Board Network

TheWhiteElephant · 02-14-2011, 10:25 PM

Ok, I have decided on a pair of Dynomax super turbos. I have to decide between case lengths of 14" vs 20". I'm going with 2.5" inlet/outlet, my engine is all stock, using ram's horns. The rig is a '73 long bed K20. All else being equal, is there any real difference in the 14" case length vs the 20" case length?

Thanks.

The shorter the muffler, the louder it is. I don't know if theres a performance difference though between those sizes.
