You rarely read anything beyond skimming through Tommy. I can pull up several posts where you ask me questions that I've already explained or answered within the post.

You assume its BS because you havent read any of it. So to me its BS that you say its BS. You dont know what your talking about.

You can tune collectors for a full exhaust and you get similar results.

Wes: you cant go wrong with flows (even though everyone has em) lol

Velocity will have 90% of its efficiency within the headers only. Its theoretically impossible to have the same velocity passed the collectors with the entire exhaust being the same diameter. In order to maintain the same velocity the exhaust would need to get smaller and smaller toward the tail pipes.

If it was all about velocity then there would be no need for scavenging. A simple single exhaust would work if that was the case.

Whats wrong with that?

H-pipe and Flowmasters are my personal favorite exhaust for a Mustang. Love it. I could care less if 50,000 other cars sound the same way.

Its a Mustang,.. Mustangs are a 'Me TOO' car. It means everyone and his mother can afford one,.. thousands upon thousands of them on the road. What ever you think you can do to make yours original has more than likely been done a 1000 times already.

Just use common sense. Put a decent exhaust on it and be done with it.

try the MAC muffler. its chambered like the flowmaster but with a little lower tone. sounds great with a x-pipe w/o the raspy sound

my personal favorite has always been Borla. ran em on 75% of the vehicles ive had, the other 25% was always straight pipes. cant go wrong with the XR Borla mufflers man. back pressure is one of those things that the queer racers like to blame on wen they lose. its true u lose some hp/tq downlow but wen ur wide open ur not losing anything, ur gaining. couple gaggots already said, no restrcition=more power, cant get no truer than that other than sayin theres no replacement for displacement.

Actually believe it or not.. the Thrush chambered mufflers dont sound bad and IIRC they are like $29 brand new. If I needed mufflers badly and really couldnt afford flowmasters I would shoot for either Spintechs or Thrush mufflers. Both are very affordable and should be well within most budgets.

I personally would not use both the Dynomax bullets in conjunction with chambered mufflers. I think it would sound ridiculous in my opinion. I had Dynomax Bullets on my 93 when I first got it. It didnt sound right to me. And every time I was at a light and I saw a cop car I was half expecting him to pull me over for loud exhaust. I forgot who I sold them to. I think Barry B came here and got them,.. I tossed in some tail pipes as I almost always give something away for free to everyone who has ever bought from me.

I've said this in at least a dozen previous posts. If your looking for a specific sound or are just unsure,.. hang out at car shows, the race track, or regular car meets and when you find a car that sounds good, walk up and ask the guy what he has. Then emulate it.
