Catback install - how high does car need to be lifted

[jmasin]

Hey all,

I know this is a low-tech question, but it is more an experience question...

How high does the GTS need to be lifted to easily do a catback install? Can this be done on stands?

I ask because the vette has these annoying one-piece over-the-axle pipes which require almost 3' of clearance to easily wiggle out, so not really a garage/jack-stand job.

Thanks,
Jon

"To do it easier" you should have a proper safe lift that allows you to stand under the car and be at eye level around the side sills. Some have done it lower to the ground but not so easy on your back etc.

What he said! If you have a stock system, it bolts in using 3 sections, 2 sides and one rear. You should have no problems removing it. I have done it on the stands, but I do wish that i had a lift.

go out and buy the 10 inch race ramps with removable sides and rear 10 inch stands and you will have enough room for the exhaust and even removing the transmission

OK thanks guys, so can be done on stands but easier on a lift.

There's a corvette racer within 10 minutes of me (LG Motorsports) who can help me out, I'll chat with them.

Yes. Much easier when on a hoist. It is not the easiest thing to pull the pipes out from under.

When I first rear the title I thought you were thinking a lift kit for the car as the new system was going to hang lower. Lol

Now that would be some funny sh**...

Catback install .... do you guys use the clamps that come with it, or is it better to have it welded together

 

[jmasin]

I'm going to clamp in case I ever need/want next step with cats etc. I'd bet most use the clamps.

 

[plumcrazy]

just be careful with the clams rubbing on anything

Hey fellow neighbor. Where you been? The clamps that come with a new system are great. Use those as they work fine. Welding is not needed and just more work.

 

[Mopar Boy]

Yeah. Don't weld. When you decide you want to do the cats (you will get there, only a matter of time!!) You will be happy you did not weld them on!!

Oh, can I make a suggestion? If you already have everything ripped apart, spend the extra 30min and do the cats. I know it is also a few extra hundred for the cats, but you will be so much happier with it. You do not get the full sound effect of a performance exhaust when you still have the factory cats in. And your interior will be so much cooler.

i used 2 1/2 inch wide band clamps....no problems yet

Your right about the Vettes. I have a lift and remember what a pain that back half was to get out. The Viper is a piece of cake to work on compared to the Vette in every way.

Dunno how different the GTS exhaust is from the RT/10, but I did the Corsa cat back last weekend with a low profile jack and two jack stands. Wasn't bad at all, and took 4 hours. Worse part was taking the cat clamps off. I did use the clamps that came with the kit and they are excellent quality. Go for it on your back!
