michael2938 24 Report post Posted September 6, 2014 I have pretty much decided I want to buy flowmaster 50 series delta flows for my car. The going price seems to be about $114. Does anybody know the best place to buy mufflers at a low price or know anybody offering discounts? Thanks, Mike Quote Share this post Link to post Share on other sites
Powershift 19 Report post Posted September 6, 2014 I have some 40 series I just pulled off my Mach 1. I'll go $100 plus shipping. http://www.1969stang.com/mustang/forum/showthread.php?t=16494 Quote Share this post Link to post Share on other sites
michael2938 24 Report post Posted September 6, 2014 Thanks for the offer, but I am pretty set on the 50 series delta flows. I am afraid the 40's would be too loud for what I am looking for. Curious though -- what did you replace them with and why? -Mike Quote Share this post Link to post Share on other sites
Topless69GT 28 Report post Posted September 7, 2014 I had the 40's on my 67 and they were way too loud. They sounded great going down the road but the interior noise was horrible. You could not even talk to someone in the car. I could have put some sound material in the car but it was a 63,000 original car and I did not want to tear the interior apart.
