xcelr8 Posted October 23, 2004 Report Share Posted October 23, 2004 Hey Guys- Just an FYI. I got tired of listening to my droning Flowmaster and went back to the stock muffler. The absolute best time (G-timer) I had ever had with my truck prior to sitching back to stock was 13.30 at 102.1. I ran it this afternoon with the GM muffler back in place and ran 13.08 at 104.7........and I can still have a conversation on my cell phone. If you're going with aftermarket exhaust avoid flowmaster. Link to comment Share on other sites More sharing options...

If you're going with aftermarket exhaust avoid flowmaster. <{POST_SNAPBACK}> Or just avoid the 40, 50, 60, and 80 series Flowmaster mufflers. The 70 series big block mufflers are just fine (I have one and it is great). Link to comment Share on other sites More sharing options...

deezel Posted October 24, 2004 Report Share Posted October 24, 2004 xcelr8, thanks for posting your results. Its real-world testing by actual vehicle owners that gets my attention when it comes to evaluating possible modifications. Link to comment Share on other sites More sharing options...
