Guest Eurolumina92 Posted February 9, 2004 Report Posted February 9, 2004 i'm looking into buying a new muffler and was wondering what would show the most power gain for the dollar borla, dynomax, or flowmaster. i don't want to really go with a staight through muffler scince i all ready have no cat which got rid of all back pressure i did have im leaning toward a 40 or 50 series flowmaster just to regain a little back pressure but im not sure. let me know what you guys think thanks again euro lumina92 Quote
maybe2fast Posted February 9, 2004 Report Posted February 9, 2004 I have no cat and a Dynomax muffler (not the straight through) the one with the S flow through. The car runs great and sounds throty as hell. it sounds really good you will be surprised! 1990 Lumina Euro 3.1 Quote
godofthunder Posted February 9, 2004 Report Posted February 9, 2004 I have a cat, and about to change to a dual dynomax super turbo setup. Glad to hear someone else has them here. You cant get a sound clip, could ya? jon Quote
5speedz34 Posted February 9, 2004 Report Posted February 9, 2004 I hear 40 series is tits on the 3.1. Quote
EurosportZ34 Posted February 9, 2004 Report Posted February 9, 2004 I'm going to get Flowmaster 40's for my 3.1L. I've also heard that combo before, it's very nice! 8) Quote
Z34door Posted February 10, 2004 Report Posted February 10, 2004 40 series on a 3.1 ..... SOUNDS FUCKING MEAN.... i have a hi flow cat bc CT sucks Quote
TeeJay3800 Posted February 10, 2004 Report Posted February 10, 2004 I have a 40 series on my 3.1 with no cat (just 2.5" straight pipe) and I can personally atest to the fact that it sounds damn good. 8) Quote
TeeJay3800 Posted February 10, 2004 Report Posted February 10, 2004 I disagree. There is some added power to be had by installing a performance muffler. Stock mufflers are very restrictive, so replacing it with a much better flowing muffler will free up some HP. True, it is probably less than 5% so you won't feel it in normal daily driving. Also true, you will see far more gains with a complete cat-back system (or not using a cat at all, which is another major source for flow restriction, especially on a high-mileage converter). Quote
gp90se Posted February 10, 2004 Report Posted February 10, 2004 Im sick of the flowmaster noise, my 3.1 was running 2 1/2 dynomax super turbos with a catco cat, throaty but raspy. borla is nice but $, I say dynomax. -Jeff Quote

Guest Eurolumina92 Posted February 10, 2004 Report Posted February 10, 2004 thanks for the in put and i can see the the 40 series flowmaster is the way to go and i think it will sound the best but i am still willing to hear more input thanks againg eurolumina92 Quote

maybe2fast Posted February 11, 2004 Report Posted February 11, 2004 Dude Dynomax, super turbos are like 40 bucks apiece and sound mean as hell, they get louder as they are used (breakin time) flows are a bill apiece! go with dynomax! Quote
gp90se Posted February 11, 2004 Report Posted February 11, 2004 $40 each? shit i payed $22 each at advanced autoparts last year. -Jeff Quote
Scannerman Posted February 11, 2004 Report Posted February 11, 2004 well flowmaster's aren't the best flowing muffler's get something that's a strait thru. flowmaster's aren't strait thru. Quote
J Posted February 12, 2004 Report Posted February 12, 2004 anyone want a new exhaust from the y pipe back with turbo muffs? It was made last summer by a local exhaust shop and i decided i want it much louder than it is now because i am only driving the car on short trips and in the summer so i don't have to hear it drone all the time. Let me know. I paid about $200 so make a offer it's clean as hell never saw winter just some rain. later jay Quote
mfewtrail Posted February 12, 2004 Report Posted February 12, 2004 well flowmaster's aren't the best flowing muffler's get something that's a strait thru. flowmaster's aren't strait thru. If 40series original Flowmaster mufflers are adequate enough for a mustang running 12 second ET's, I think they flow plenty for any car on this board. Quote
Euro Posted February 12, 2004 Report Posted February 12, 2004 im going to go with dynomax super turbos this spring. should i get 1 or 2? cant decide. Quote
