Anyone done this combination yet? This is for the fiancee's Tahoe so having no cat's is not an option(the smell and I want it to be legal).

Looks like a tight fit. Guess the main thing is going to find cat's small enough to use?

Any help or suggestions would be appreciated.

 

I don't know about the cats, but the LPP headers look top notch. I'm hoping to get a pair soon.

 

I too would like to get a set of longtubes with cats and wondered the same thing. What are the dimensions of the y pipie to the slip fit on the header? Anyone who has this could you please measure for us.
