flowmasters ****,they make no power...
Look for a muffler that has a straight through design...
I have been dragracing for 20 years and any real racer runs a straight through muffler...Flowmasters are not straight through and in my own testing were
substatually slower than Dynomax - I run dual 4" Dynomax's BTW //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
