Dual exhaust on 3.1 V6

[Aron Nance]

Have asked a local muffler shop about the possibility of installing duals on our new/old '94 Cutlass Convertible. He said no, that only the 3.4 came with them, and they aren't "true" duals. The picture he showed me out of a muffler manufacturers catalog seems to back this theory up, shoiwng a muffler with two "outlets", and then two pipes running to the rear of the car. I'm wondering why these same parts (for the 3.4) couldn't work on the 3.1, other than the fact that the plastic rear bumper facia does not have the additinal "cut" on the driver's side for the pipe to protrude. Has anyone tried this conversion?

The guy is a moron. Find a different shop.

Like Jeremy said, dude is a moron. They aren't true duals, thats true. But doesn't matter which engine you have, plenty of 3.1's have the dual exhaust.

It's bolt on, just need the add the dual cutout bumper cover (or make your own cutout) and add the drivers side hanger.

[Psych0matt]

do it, and then go back and laugh at the guy when you show him

If you go into the Maremont E-catalog you can see their OEM replacement system for the Grand Prix equipped with the 3.1. (The Walker catalog will give you the same result). The system is essentially the same as the DOHC application with a few exceptions up front where downpipe dia is concerned & the addition of a resonator. All the piping at the rear is the same dia. irregardless of what engine is up front.

It is possible.. easily, this is one thing I would like to do to my car, but I still have to come across a bumper cover with the dual outs cause I don't want to cut mine.

Just have a shop custom bend an exhaust for you...

meanwhile: back to the thread at hand

Oh it's used here occasionally too, but it still isn't a word

I'm guessing the guy just didn't want to do it. Shit, I've personally seen HHRs with duals on them, which never came that way from the factory. So I know you could do it on the 3.1...

This has been done. Get the y pipe from a junkyard and grab the hangers and take it to another shop and have it installed. Any 88-96 w-body y-pipe should work.

 

Once it's done take it to that shop and show the guy. 3.1/3100 could get dual exhaust from the factory.

[AWeb80]

you can get custom exhaust. I had mine done from the Down pipe back.

and that is one of the sickest exhaust systems I have seen on one of these cars

[AWeb80]

haha, thanks. It's not much. ~$400 worth and cheap aluminized. the cat was the most expensive part.

[LuminaPower92]

I redid the exhaust on the Lumina. Ill get a pic of it underneath. Costed me 300 bucks to do from the cat back with 2 magnaflow knock off stainless steel mufflers and using stainless steel piping.

 

[94 olds vert]

That is sick. Really makes that Lumina mean.

[intern8tion9l]

i <3 aweb's exhaust. i'd throw down $400 tomorrow if i could find a shop to do it for that price

[Nick1234]

I think i ordered mine for a 93 grand prix gt? and then added some pipe across
