I have a standard 2 chamber Mac Cat back exhaust on my 90 GT. It is sooo f**king annoyingly loud at cruising speeds that it gives me a head ache! I HATE IT!! Needless to say Im looking for a change. I want a performance muffler that is nice and quiet in the interior, but with a nice low rumble on the outside. (If there is such a thing). I've been looking into Magna Flow, Spin tech, and Dynomax. Spin tech claims to get rid of the drone at cruising speeds. Magna Flow has the "wide open performance" and exhaust tone that the 5.0 mustang mag crew likes. As for Dynomax, im not sure what to think. Also, are there any fitting or clearance problems? All info is greatly appreciated. Thanks!

 

Well hate to say but u know who has an even better selection for your situation??? Flowmaster... you saound like u need the delta flow series.... from what i understand it's exactly what your lookin for...

 

I would deffinetly go with a 2 chamber flowmaster believe me is sounds nice. It sounds like bubbling water. Go for the flowmasters.

 

Yea they r great but 2 chambers r too loud for what he is looking for... all in all i want the flowmaster sound!!!

 

i would say to get flowmaster. i think it has a nice sound to it and a lot of my freinds have it on thier stangs and it SOUNDS really nice, so go with the flowmaster. ----------------

Funny stuff that's good lol

 

Hey i thought i'd give yall a word of warning on flowmasters. They are great sounding, and their quality is excellent, but DO NOT get them welded straight into the existing stock cat-back system. This is a BIG NO NO. i had that done (back when i was stupid) and the pipes had to be sleeved because the flowmasters have a larger diameter than the stock mufflers. Sleeving the pipes can causes massive amounts of exhaust leakage (not to mention cracked welding down the road), and now i'm having to replace the mufflers with a full-out flowmaster cat-back system, which should have been done in the first place. They have a better sound anyway.

 

ouch that sucks... too bad man

 

i would have to agree with everyone else and say that 2 chamber flows are the way to go. as well as some form of "X" OR "H" pipe with a high flow cat system

 

If you want a "Quiet" performance style muffler but gets loud when you get on it; get magnaflow. If should get rid of any 2000 rpm range drone.
