Will a Flowmaster AT kit for LT1's fit LS1's? I found an AT that's slightly used that was originally on a 95 LT1. The kit is 3" outlets like the kits made for our LS1's. The part number is flo 17274. Will this kit bolt up to my car with little or no extra work? thanks

Would you know what exact changes or tweaks would have to be done? I looked at Flowmaster's website and looked at diagrams of the kit for LS1's and this LT1 kit. It looks to be very similar except the LT1 kit has an extra bend right behind the Y pipe. Would the LS1 kit require any extra bending to compensate? There is a shop here in town that does mandrel bending, but they seem to charge an arm and a leg. The guy wants $200 for the kit, and the cheapest I can find a new AT kit is $300 from Texas Speed.

I had the Flowmaster AT LS1 kit on my car and then put it on an LT1 car. The lt1 car's y pipe is in a different location. Therefore, the intermediate pipe is bent. With my kit # 17999, the intermediate pipe was curved over the axle, then was straight all the way to the y-pipe. Here is a pic.
