QTP LTs with Stock Cats

I've pretty much decided on the QTP LT headers. However, I don't see how the collector mates up to the stock cat. Is there an "adapter" or do you have to use some other aftermarket cat?

No you cant use the stock Y pipe with Qtp's you can either buy and aftermarket ORY or a catted Y pipe. You could also have something custom fabed up. But the stockers wont work...

You need their Y pipe, its designed to fit correct.

If you havent considered, try Dynatech LT's w/ their y pipe, 1200 through new Era (Sponsor)

Sorry I didn't specify. This is going onto an 82' Corvette with an LSx motor. It most closely resembles an F body setup, except I have a true dual currently using the stock manifolds.
