i bought the ebay exhaust. it does not appear to come with a test pipe. three questions. first with a turboback and tune will there be any difference in power between running a test pipe and the factory cat. second will the factory cat bolt up to the ebay exhaust? the test pipe below claims to eliminate the check engine light. look like it would really not trigger the check engine light

As far as power goes you should see a difference between stock cat and test pipe. Whether it is enough to be worth it or not is up to you.

Everything should bolt up fine to the stock cat.

That test pipe looks like it should eliminate the P0430 CEL that comes with a test pipe.

 

thanks!

 

removing the cat yeilds about 5 to 7 hp. Nothing serious.
