hey guys I have a question. I think my passenger side cat is clogged . If I were to replace it with the highflow catco replacement would it have any ill effects on the car and would it horribly unequalize backpressure between the two banks ???

 

I dont like the idea of having a difference in power between cylinders. The stock cats dont flow all that bad so i dont think you would notice a difference but why not change em both while you're at it. They don't cost all that much and since one clogged, the other is probably clogged somewhat as well.

 

Definetely change both at the same time.

 

thanks , guess im gutting the lil bastards till I have money for a ypipe with cats

 

Don't gut. Replace with pipes.

 

ok im jamming a pipe thru those lil bastards lol , all we have here is visual inspection .

edit , im pretty sure the stock y-pipe runners are 2.5 inches in diameter right ?
