My car is white, and I get black all over the rear end....Little splatters, but mostly it stained above the exhaust tip itself, I guess I could lean it out a % or two, but would rather be safe than sorry.

 

As far as the replacing the cat law goes, you hit a rock or something and it dented the cat and put a small hole in it so you had to buy a new one. Most cops dont care enough to even hear the story

 

I LOVE my UR high flow cat - its an amazing unit for the price - AND I not only did not loose any power on the dyno - I picked up spool up !

here is my dyno sheet on pump gas with the UR cat

 

How is the Ultimate Racing cat different from say the 3" hi-flow cats such as on the Buschur or Vishnu exhausts? Does it really flow measurably better? Different construction?

 

hey ray, would I happen to see your car when I was in Hong Kong. I was driving towards Tuen Moon and I saw a Yellow Evo in the back of me. I believe there was another car with the yellow evo. I only saw a black Evo VII in Hung Shui Kiu, Yellow Evo VII towards Tuen Moon, white Evo VII in Mong Kok near Loong Wah Motors, and a black Evo VIII in GT Sports in Yuen Long.

 

I hear ya about the supra. Mine stank sooo bad with no cats. ughh
