True Duals that exits out the rear? Ok, I've been searching on here for over an hour, and I can't get a straight answer on my question. 
Does ANYONE make an over the axle true dual set-up for LT1 cars? I want to have TD's put on the car, but I don't want to dump it under the car. I'd also perfer to have the mufflers mounted behind the axle. Some please have some good news for me. Thanks!

heres a post i made a few days ago. tspence45 has had em come out the back under the axle rather then over. a few guys have done it successfully. in order to get it over the axle you need to get panhard bar relocation kit.
personally i am leaning towards going under the axle. someone on my post made a good point...unless something gos stright under the car without hitting the tires...shouldn't hit anything goin under

That is a good point. I'm still open to the over axle set-up, but it looks like the under axle set-up would be much cheaper. I still want to have the mufflers mounted after the axle though.

My setup was pretty inexpensive, and like said, it was taken under the axle. After I had the mufflers moved I've had no issues with ground clearance, and it sounds meaner than hell. I'd suggest some knock-off Flowmaster single chamber mufflers. You can get the pair shipped to your door for around $60, and they're the exact same thing as the Flows. I couldn't be happier with my setup.

Performance Auto Fab, a sponsor here, has done several TD systems that exit over the axle out the back... Theres at least one set up I know of that had Borla round mufflers mounted cross ways in the back behind the axle. I think it was on a Red SS...The set up looks great. I don't know of any kits, though. The PAF set up looks incredible....

check it out... This looks like it only fits on a 95+ car with the dual cat Y pipe, not on LT...

Relatively minor mods to make it fit LT's. Mine really didn't take that much work to do.

These are all great ideas, but I think I'm gonna try and go the route that tspence45 went. I just watched the vid he put up, and that set-up sounded like pure sex. lol It makes my Loudmouth 2 sound like crap.

lol. Thanks. It actually sounds a little bit better now that I had the mufflers moved back too. The only thing that I don't like about having the mufflers moved back is, it's quieter inside the car. I think it's actually louder behind it now though.

A competent exhaust or fab shop should be able to do the exhaust without needing a padhard brace relocator kit, but it would make it easier.
The Bassani is the only pre-made kit like others said above (I bet it sounds amazing though), but a shop would probably do it for a lot cheaper. My whole setup cost around ~700 with mufflers.

That's kinda what I'd perfer. The LM2 I have right now sounds great, but it pops, and gets alittle raspy at mid-range. Of course what do you expect with bullet mufflers. lol About how much did the shop charge you to fab, and weld up you set-up?

I had them do the LT header install, plugs, wires, fab up the x, and I also bought the piping to go under the axle to out back. All that together was $300. They said it would've only been $200, but they had so much trouble getting my old Edelbrock shorties off. But, I also had to go back to get my mufflers moved. They had to use all new piping from the axle-back, so they charged me another $120 for that.

@ tspence45, Do you happen to have any pics of your set-up? I'm curious to see how your mufflers are mounted. Did you get those 13" long single chambers on ebay?
