-- Posted by tempoluvver69 at 11:34 am on Aug. 7, 2008 Right now i have a single flowmaster delta 40 that splits to 2 pipes straight out the back. Anyone know how much louder a replacing it with a single glass pack would be? Im also curious if it would be louder to run 1 glasspack split to two pipes or run two glasspacks after it splits... -- Posted by ss454 at 12:23 pm on Aug. 7, 2008 Since glass packs are pretty much flow through, I'd only guess they would be louder.  I would just search youtube videos to see what's louder. -- Posted by hinshawwrx at 2:51 pm on Aug. 7, 2008 It'll be a good bit louder. And flowmasters blow in terms of performance. I'd rather just get a cherry bomb turbo muffler instead of that junk -- Posted by ss454 at 4:10 pm on Aug. 7, 2008 Quote: from hinshawwrx at 5:51 pm on Aug. 7, 2008 It'll be a good bit louder.   And flowmasters blow in terms of performance.

Flowmaster is a chokemaster. Shitty CFM flows -- Posted by i r sekz at 11:04 pm on Aug. 7, 2008 I love Magnaflows, they sound amazing no matter what car they are on and they are extremely good performance wise. -- Posted by tempoluvver69 at 7:01 am on Aug. 8, 2008 Hinshaw, whats up with you and flowmaster? Idk if you are right, but even if you are, the power difference is not significant. I doubt there is a 2% difference in power between a flowmaster, magnaflow, and cherry bomb. -- Posted by hinshawwrx at 2:55 pm on Aug. 8, 2008 Lemme see if I can dig up the CFM ratings of the popular mufflers.
