Mustang H-Pipe to Impy Tails Questions

[Tiggie]

I really need to put my headers and Mustang H-Pipe on. My stock H is leaking fairly bad. I was gonna wait until I put the new motor in, but that is looking like it is gonna get pushed back a while. Paint and the slicktop conversion are #1 on the to-do list right now.

I need to know what kind of mufflers and intermediate pipes to run with the setup when I use Impy tails. I've heard S-10 midpipes work. How are the mufflers as far as inlet/outlet offset?

I'm not that concerned with the mid pipes, I think an exhaust shop should be able to fab me up some for a decent price.

u need 2.5" ofset ofset mufflers, a pr of mustang midpipes....cheapest is flowtech.....50 pr shipped from summit, and a pr of 2.5" 18" long extension pipes...about 5 bucks ea....line it all up, cut the extension pipes to fit......need some extensions in the back too if your doing it yourself

if youre going to an exhaust shop, i would just get the tails and the mufflers, drive there with an open mustang h pipe on the car lol

Yeah, most exhaust shops should be able to fab up a custom mid pipe for you in place of the extended Mustang setup. Its pretty much just a straight piece of pipe with a flange on one end. There is a slight little bend in the Mustang part, but its not anything that a decent shop can't duplicate easily enough.

How long do the mufflers need to be?

[83countrysquire]

i was thinkin of runnin straight slps is it possible

[mrltd]

Mufflers can be any length, you just adjust the midpipe/flowtube length.

Thanks for the replys!

Hehe I am looking forward to the open H-Pipe trip to the muffler shop . So offset inlet and outlet is what I need and the muffler shop can handle the rest between the muffs, H, and tails. I haven't decided on muffler type yet... something chambered probably.

Summit Turbos are the cheapest muffler you can buy, and they're quiet. If you want loud, I suggest Dynomax Bullets.

I'm going for fairly loud. It's not a daily driver and the sound is what makes people look at the car .

[88Vic]

Then the Bullets are what you want. The Dynomax website claims they're 2-4 db's quieter than straight pipes.

Ouch. I've got 19" Walker SoundFX mufflers (budget OE replacement type) with a Mustang H pipe and 2" tailpipes on the Squire and it's still a little loud to suit me. The X pipe on the Colony Park with 2.5" tailpipes and very similar mufflers is fairly quiet, though.

Blown-out eardrums, anyone?

Maybe Flowmaster 40 series?

I am doing duals for my ma's CV. Perhaps I will have that installed before you do yours. I have BBK Mustang shorties, BBK H-pipe w/cats, two 2.5" flanges w/ 2.5" collectors, two 2.5" cut outs, 8' of piping, Summit Turbo muffs, custom bent tails, and 4" resonated exhaust tips. I am also going to play with the 94-96 Impy 2.5" cat back to see if it fits as good as what I got. So you want a loud chambered muff eh? 88Vic had a good suggestion, but you could also try Thrush 2.5" welded chambers out of Jegs (part# 289-17659), they are relatively cheap ($29.99 each), and they look like they're loud. I got a Thrush glasspack for my Chevelle and that's plenty loud (though I did install a cutout for a little more hehehe). I was also told that the Flowtech Warlock muffs (part# 387-50552) are loud too; and that's when the caps are closed, but they are twice the price of the Thrush muffs. Hope this helps and get some sound clips when you're done!!!!!

a longer pair of magnapacks???

[1987cp]

Walker does offer offset-offset glasspacks. Only trouble is, I'm not seeing 2.5" in/out in my catalog right now.
