ORP?

Is there a company that makes a off road pipe to eliminate the cat for a GTS?

Just take it to a muffler shop and tell them to weld in a straight pipe in place of the cat. I wouldnt do it though. The cat is already extremely high flowing, and you may bet backpressure issures. If you want more air flow have a straight pipe welded inplace of the resonator.

i think you would only get backpressure issues if the diameter of the piping is too big..the right size would be fine...if the cat is already high flowing, then eliminating wouldn't cause a backpressure problem when the flow isn't so restricted on the same piping

cats always restrict
and its not a high flow cat like you may think
going catless is always better.
