I need to find some fake cats. They can be weld in or bolt in it doesnt matter but they have to be steight through not hollow. Do they sell these? Some that were 2 peices and I just weld them over the pipes that would be perfiect.

 

There's a set of gutted SLP's on Ebay right this second.... hurry.

 

Modify your stock cats. Make the hole on each end bigger and slide it over the y-pipe then get it tack welded in place.
