Nope, I have two high flow cats. My exhaust ties in right before my borla muffler and they spilts apart after. I need to make a better video but here's a couple clips of mine.

Hmm, so, I would go with 2.25" dual cats then for my set up?

 

I went with 2.5" and had reducers welded into them to fit the 2.25 downpipe. The 2.25" would be a direct fit. Here's a couple pics of mine.

 

ohh okay. well i requested information on both the 2.25" and the 2.5" so i will get info on both of them. thanks for all the help though

 

My pleasure, good luck with it.

 

im going to get a quote when i'm on days off starting wednesday so i will let y'all know

 

ha thats playmakers truck, hes one of the members on here.

 

haha i knew it looked familiar, well, nice sounding truck playmaker haha

 

Hate to be a pest, but I am thinking of 2.25" High flow cats to go with my exhaust. Say I went 3" totally to the cats tehn used a reducer to the 2.25" required for the muffler inlet then 2.5" out the muffler. That, in theory, would create a venturi effect in the exhaust increasing velocity into the muffler. What would that do for sound and perf? The reason I am asking this is because essentially, we are creating a restriciton and would negate the effect. In theory. I have attached a picture of the venturi tube for those wh do not know.
