BigMike Posted May 6, 2013 Share Posted May 6, 2013 Ok i am thinking of putting some flowmaster 40 series on and a new exhaust next week or so... And my question is this.. What if any flowmaster series do you guys have or recommend? Quote Link to comment Share on other sites More sharing options...
David Mau Posted May 6, 2013 Share Posted May 6, 2013 It really depends on how loud you want your car to be - both outside and inside. When I got my exhaust system replaced in 2006, I went with Flowmaster Delta Flow 50 Series mufflers. Their exterior sound is considered "moderate", while the interior sound is fairly quiet and resonance is non-existent. It's a great combo. It's my understanding that their mufflers with the name "Delta Flow" are the ones to get if you don't want interior resonance. We've driven the Monte to a couple of Western Meets that are about a six-hour trip each way (even when averaging 90mph for some of it), and it was nice to converse at normal volume even with the windows down and arrive without headaches. I believe the Flowmaster 40 Series are considered to have "aggressive" sound, but I think they're also available in "Delta Flow" versions, too. Check out their website at www.flowmastermufflers.com . I hope this is of help. Dave Quote Link to comment Share on other sites More sharing options...
7tonemonte Posted May 6, 2013 Share Posted May 6, 2013 I have the Delta Flow 40s on my car. As Dave stated above, no interior resonance ( annoying droan at highway speeds ) it's easy to have a conversation with someone in your car! They have a nice sound to them as well, my car is only a fairly stock small block, I'm sure Dave's car would be much louder with the 40s!

monte70car Posted May 6, 2013 Share Posted May 6, 2013 Had 30 series on my until they started breaking down from the inside only been on the car for 14 years. Going to pick up so cheap mufflers just so the car for make the Eastern meet and then think about a change. Also have the Delta 40's on our 57 Nomad with a small block then a set of series 44's on our 70 El Camino. Quote Link to comment Share on other sites More sharing options...
black07ss Posted May 7, 2013 Share Posted May 7, 2013 14 Years for a muffler seems like it held up great? Maybe it's just me Quote Link to comment Share on other sites More sharing options...
