I have 40 series flows on a 02 Gt. I was thinking about changing them out for some magnaflows. I have them on my truck and they sound great so I can only imagine what they sound like on a stang. If I do change what kind of hp differences will I notice? I know it wont be alot but I've got a prochamber waiting to be installed after the mufflers go on. Ive heard a prochamber with flows before and it sounds great but what would magnaflows sound like with it. Ive always heard to go with a hpipe or prochamber with a chambered muffler and a xpipe with straight thru mufflers but i"m just tyring something a little different. thanks to all for help and opinions.
Chambered vs. Nonchambered hp?

I have magnapacks with a catted X pipe. I called magnaflow tech dept, and they said the whole kit adds about 24 horsepower. They cat back alone adds 14hp. My sound is great...the X pipe made the rumble a little lower.
My friend gained 6rwhp alone by switching out his flowmaster catback for a bassani catback on his '01 cobra. (n/a at the time too)
any straight through muffler is going to make more hp than a chambered one, i believe turbomustangs.com got 25 hp by switching from flowmasters to dynomax ultraflos. obviously that was forced induction so gains on an n/a car will only be a fraction of that, but still shows gains are possible by switching to a straight through muffler.

I agree.Its all about sound.
dont believe the hype in the adds.In my n/a days going from flows to magnaflows (both catbacks) I LOST 7rwhp..But that was my car..

The horsepower differences are so minor that it doesn't really matter. Go with what sounds best, unless you have a 600rwhp monster.
