I have a bone stock 85 Mustang GT and I removed the factory Y pipe and replaced it with a 95 mustang H pipe. Now with just the cats and no exhaust it seems to have lost its low end. Should I put a stock turbo style on or high flow race muffler? Which muffler would work better? I don't think sound control will be an issue due to the preheaters and the cats or could it still be too loud w/ the wrong muffler?

It's a matter of preference in terms of sound. Though Flowmasters produce the "dreaded" resonance at 2,000 rpm, I personally like the sound of them. It you want big-block sound and don't really mind the resonance (it really isn't that bad) go w/ some 40 series. If you want a milder muffler, some 50 series will work too.

My 40 series dont really resonate at all, I think the full tailpipes have something to do with that too. I used to have the 50 series and they were very tame, great for a street car.

I don't much care for the Flowmaster sound. The dynomax turbos are some great mufflers, and I have some Thrush turbo's on my '67. I know I'm not impartial but I still think my car is the best sounding muffled/"quiet" car I've heard.

When I hear flowmasters the first thought I have is a ratty old pickup truck. They flow well, but they're overdone. I think you'll be happy with the Dynomax or thrush turbos. They aren't loud at cruise, (and let some pop through at idle,) but they get quite a bit louder and sound great when you're on the throttle.

Well, it's plain to see from the H-pipe you put on you don't care about performance. So go with a sound YOU like. Listen to a few cars and ask what mufflers they are running. Get the ones you like. A lot of people put the SLOWMASTERS on their street cars, I don't care for them or their sound. If performance were your main concern I would recomend the Hooker MaxFlow as they have been proven to give they highest flow of any muffler out. My son ran his 93 LX at the track one week with SLOWMASTERS and ran a 12.80, We changed the exhaust and put the Hookers on and ran a 12.56.
But a lot of people don't like the quiet sound of the Hookers. They give the car a deep tone like a magnaflow or dynomax.

I'd pick some nice turbo's. Flowmaster's sound best w/ a tight motor and lots of compression IMO. They can make anything annoyingly loud though. I never personally had a big problem with the resonance in a fox body though even w/ the 40 series. My older cars seemed to pick it up more.

I have Dynomax bullets on my Bird, and love them. I do not have cats, so they are a tad loud, but I have had them on for 2 years, and no tickets.

Hear is a sound clip of it.

I'll second that motion on the fastback!

I went to a local exhaust shop and put on some unknown ( I think they are the IMCO fully welded race muffler) race style muffler and the sound is a touch deeper than stock. I am very pleased! These same mufflers were on a Chevelle and they took them off because they sounded like glass packs. I think the factory H-pipe w/ the converters let you get away with about any kind of muffler. They have a slight bit of resonation at 1800 RPM but it is very minimal. I was scared it was going to be too loud!!!

351C long tubes 3" pipe, dumps at the axle.

When my buddy first heard it today his first words were "Its perfect, Not too loud. JUST right! Perfect for a cruiser"
