Question installing LSJ exhaust (one piece)

I got a LSJ exhaust, it hasn't been cut. Do I have to cut it then weld it back together or I can just leave it and will be bolted on perfectly?

Thanks

You can get it in without cutting. It takes some manuvering but its doable. However it may be worth your time just to cut if if you have access to the tools for that.

Cut it and clamp it. It will be alot easier than dropping everything down in the back.

Clamping sucks.

If your gonna have to cut it, weld it back together.

the ebay ones u cant bolt on, they are not 1 piece, and to the OP u have to drop the rear torsion bar to get clearance...not remove it...just lower it...basically remove the rear shocks and springs, raise the car from the side, and it should give you the room u need, although it would be soo much easier to cut and weld, but if you dont wanna deal with it, its duable, just you will be scratching your head a few times trying to think of a good angle to slide the exhaust in

i just had to cut, i didn't want to go to all the trouble of removing torsion.

What do you guys think about running 50 shot of nitrous on a stock LSJ Exhaust, DP, mani?
