on my 96 w/ 4r70w i have tried 2 different mid pipes.... the first was a MAC and the second was BBK.... they were both catted too. i am looking for a catted mid pipe that will fit the auto.... does anyone w/ an auto have a catted mid pipe on that they didn't have to modify to fit.... b/c the 5 speed mid pipe rubs against crossmember and sags.... i have heard upr's fit well with the autos as well as SLP.... any recommendations????
thanks
