If I install the Stillen race pipe will my car pass the state of Washington emissions test?

 

it should if the car is really warmed up so that the main cat works. visually im not shure depends if the guy crawls under the car to look

 

Thanks for the info.
Do you know if the cattman y-pipe is any better, emissions wise? Also your impressions on the performance of both?

 

basically all the pipes should be pretty much equal. performance I cant tell you the difference between the 2 pipes since all I been around are cattman pipes but im shure the difference isnt noticable performance wise

 

I would spend my money with www.warpspeedperformance.com instead. Same performance almost half the price.

 

I would have too...

 

ida gone with budget

 

usually if they do a visual test, they dontlook at the y pipe, they just care about the main cat.

 

and what are the chances of them knowing that the ypipe is suppose to have 2 cats anyways?

 

Good points, thanks for the help guys.
