of longtubes with y-pipe with cats? if so, what type of performance gains were seen with aftermarket or stock cats? also, if anyone has pics of their longtubes with a 2/4 drop to give an idea of groundclearance would be great. Thanks.

 

I don't have any pics, but I just installed a dynatech supermaxx kit and it is nice. It includes long tubes and a catted y-pipe that is stainless. I don't have any numbers for you performance wise, but the truck does feel a little stronger. Also, ground clearence is not a problem with this kit, nothing hangs down any lower than the frame.

 

I have a bunch of Dynatech pictures I recently took. I'll get them up online one of these nights.

 

thanks for the replies guys. pics would be great. i am thinking of going with the pacesetters and fabbing my own catted y. the service manager at the dealer is an old friend but he has forbid me to delete the cats until after the warranty is up. what kind of emissions are you guys seeing with and without cats?

 

I will know in November.
