Default Need cat recommendations

I'm looking to get two cats welded into my bbk y pipe and I need some recommendations on a good low profile set for clearance.

Bullet style high flow cats. Is your y pipe 3 inches?

JakeFusion is right on the kooks...I had the tsp catted y pipe and the driverside cat didn't last long. Replaced it with a pacesetter cat. But went catless.

I bought these for the same reason (in 3" though). I just kept the portion I removed from the TSP y-pipe so I could yank them out as soon as it passed inspection
