I was wanting to hear some thoughts on this.... I have a stock exhaust on my 99 cobra. I was talking to a friend of mine who has a 2002 GT he said that 50 series 2 champer flow master muflers would sound sweet and to just get them welded in place of the stock ones. Would this sound good? Then another one of my friends said it woudl sound like tin cans :shrug: So i dunno what to think. Would this be better than going with a cat back system? I am looking to spend from 350 to 400. I am looking for a deep sounding system like a sports car should sound. But i would not like it to drone really bad. Is that asking too much? lol sound off. thanks in advance.
 
what is the diffrance between 40's and super 40's? Where can i get them? Are they just the mufflers that weld in to the stock place? do they drone? Do they give it the nice deep sound then when you romp on the gas does it sound like all hell just broke loose? I want somethign that is not loud and crappy sounding i just want something to scare people a little more when i rev it and really get on it.

super 40s are deeper and louder than 40s.

you can get them at a lot of places... www.lmperformance.com www.jegs.com www.summitracing.com or get ripped off and buy them from flowmaster directly (www.flowmastermufflers.com). When I had my flowmasters, i ordered via summitracing with no problems.

Yes they are deep and loud. most people consider flows the "Traditional" mustang sound


and yes, flowmasters can come as individual mufflers, or as a whole system which include all the piping. and No, those whole systems are not hard to install, and yes aluminized steel does rust over time. I'd only buy stainless steel for my exhaust, personally. And yes, the delta flow 40s are quieter than the original 40s, and yes, I dont like them.

I'll also make one last recommendation, if you want it scary, deep, rumbly, and loud sounding and you're dead set on flowmasters, do this.... Get a full assembly offroad H pipe, and weld in Flowmaster 10 series race mufflers. you're stock piping is 2.25 inches, so buy an american thunder system (for the 2.5 inch pipes) and swap out the 40s mufflers (put them on ebay or something) for the 10 series mufflers (buy em seperately). That'll sound good. Probably TOO good. :nice: :nice:

Anywhere i can go to hear what it would sound like?

:doh: sorry forgot. Important link.... http://www.mustangexhaust.com/4.6sounds.htm


the "1 chamber" is the 10 series flowmaster muffler. I like V8s loud, so, it may not be your cup of tea. but if you ever see me on the street with that setup, you'll be sure to get a LEAST a thumbs up!! :nice: :nice: :nice:


EDIT:

my PERSONAL exhaust setup is listed at my website (in signature). I also have sound clips, maybe they'll peak your interest into something else. (I dumped my flowmasters for my current setup with SLP). Dont forget to sign my guestbook at my website!! :spam: :D

i also set those soundclips to mustangexhaust.com and I have not heard back from them anything. my soundclips arent on their website either. :shrug: maybe i just kick too much ass?
 
I've got the 50 series(3 chamber, part of the Force II cat-back)
Loud as hell when getting on it setup w/ the Dr. Gas. I just put my stock H back on a couple days ago for my tranny TSB work, and it's really quiet. Still louder than stock, but not by much. The tone is excellent and there's no drone though...

Just my $0.02
 
I also have the 50 series three chamber. There not loud untill you crank it up but they have a really nice deep tone. But if you want loud you probably wont be happy. though i do get alot of compliments on how my car sounds. :flag:
