I'm running Thrush Glasspacks right off the headers and as of right now have no tailpipes, you can hear it in my project thread I have a video there............ http://mmb.maverick.to/showpost.php?p=944043&postcount=159 of course it's a 351 Windsor.
Hmm,I've been wanting to get headers for a while but the price isn't in my range yet so flowmaster 44s or original 40s is what I'm debating on now.
Ummm, I'm looking for something that is a bit quieter for my 5.0 T-Bird, has Flow Masters now and they suck, nasty drone cruising at 1800-2000 RPMs... They do quiet down some at 2200 or so but there aren't many places around here I can run a constant 75Mph with it...
The droning gets old with any of the two chamber turbo mufflers. I have Walker 3 chamber turbo mufflers on my Cougar with 302. Has a pleasing deep sound, no drone at any rpm. I like them a lot. I don't feel the need to set off car alarms, or announce to the neighbors two blocks away that I am coming down the street.
Dynomax's will fix that. Had a set on my 89 Ranger for years, nice mellow tone, not too loud just right. They need an X pipe or H to even em out, I ran a homemade equalizer chamber (twin 2.25" into a 4" x 12" chamber, then back into 2.25") installed between the headers and mufflers. That wouldn't fit a T-Bird though, the X or H would. My Comet has got 2.5" x 18" Turbo Tubes, they're loud as **** but they don't drone and have a nice raspy sound when you back off the gas. No tailpipes to speak off behind em.
It now has a full 2.5" mandril bent system(Hooker kit for a Fox Stang)... Current muffler shells are 17", dunno if I can get 18" under it, maybe with some tailpipe trim, they are as far forward as space allows... I'll start looking around...
For now, with the single exhaust, I'd just go with a Summit turbo muffler. It will sound good, and you can even put a dual chrome tip on the tailpipe to make it look good.
instead of spending the $150 or so on the muffler and having it installed you should buy some headman headers. I paid $149 for mine if I remember right. and Ive put cherry bomb glass packs on directly off the header and I like the deep rumble to it but NOTHING like the ROAR of the open headers I had magnaflows on my car as well at one point and hated them from the minute I started the car after getting them installed (cost me $200 to find out I hate them) thats what made me say F it Im buying headers.
ummmmm I was saying since he HAS A V8 he would prolly spend the same amount of money trying to get a sound he wants from a single muffler as he would just ditching the exhaust and putting headers on AND gaining some more power in the process I was overly surprised at what a difference the headers made on my car now I hate to close them
