The skinny on mufflers

[JaxTheDJ]

My racing buddy Rick ( who owns a muffler shop) and I decided to test all these so called power adding mufflers,so we knew what times his Stang ran in the 1/4 with the flowmasters(13.21), 2 weeks ago he welded up a set of Dynomax's and went 13.20's again.(hundredths varied a bit) due to heat track conditions etc.
This week he tested the Warlocks,guess what? 13.20's again,so when you buy your mufflers,look for the best deal and basically the sound you want cause there is NO appreciable gain from one to the other,all types tested were flow thru design with little to no backpressure. Just some info to share from a couple of guys who did the install and run test. All Mufflers were given a minimum of 5-6 runs at Gainesville Raceway . Hope this info helps with decisions you make.
