true duals exhaust pipes out the side?

[94formulaLT1]

i was wondering if it is possible to run true duals off the headers to the side of the car, infront of the rear wheel on a 94 firebird formula? I was told it was possible with about 2 1/4-2 1/2 inch pipe. But i need someone else opinion.

I really dont see why not. All it would need is some custom bends and should work no problem.

It is possible - guy in the local club has them - he has them with NASCAR boom tubes - very cool.

i was just worried about clearence..what ppe size should i use all the way back? and what are boom tubes? are they kind of like chambered mufflers that is crimped? if you know what i mean

My exhaust runs to the rear axle, and has turndowns (pointed "inward" to try and meet the local track noise limits). It wouldn't be that hard to add a bend and aim them over to the sides, in front of the rear wheels.

that is pretty nice, what size is your whole system? i was thinkin about running 2 1/4- 2 1/2 but im not sure what will work. I am also looking at the chambered exhaust mufflers in the summit catalog, its a straight through muffler that is crimped about three times, all the way down. look for yourself, people i work with tell me they sound amazing on f-bodies. it also helps that i work in a muffler shop! get these things at a discount. thanks for your help

I have the AS&M headers, and 3" extensions on the collectors, then a Borla 12" long 3" XR-1 muffler (straight thru), and then the 3" pipes to the rear axle. Its pretty loud.

Previously I had the same exhaust through the Borlas, a 3" Y-pipe to a 4" Mufflex catback. The "Y" wouldn't fit after I put the Gear Vendor O/D unit in, so I removed the Mufflex to save weight (its weighing down Joe 1320's car now ) and had Mufflex make me the 3" dual pipes.

so you can fit 3inch pipe under an f-body? if i read your post correctly..

If you are worried about ground clearance, you can buy 3" ovalized pipe and accessories

Dang.... and I thought that Mufflex was throaty. The turndowns pointed inward must make the interior resonate like a %^&*%^&*%!

Heck, 4" will fit. I picked up a BMR panhard rod relocation kit which gives clearance for dual 3" over the axle. I just run the single 4" instead.

thanks for that website, i knew there was a way to get oval tubing. ive never seen it but its the only thing that makes sense on low sitting cars. but one thing, lets say i would get the oval tubing, then my muffler will be three inch in diameter..so no matter what i do i will be scraping something. So i might just stick to regular tubing. like i said, being i work in a muffler shop, i get almost anything i want at manufacters price, its pretty nice. but not everything... thanks for your help everyone.

I went with 3"Chambered exhaust and have no clearance problems. I only used the oval pipe to exit out the side of the car in front of the rear wheels as that was the low point for me. I ran it along the trans tunnel and then out past the end of the front/center frame rails that run by the trans.
