I have searched extensively for information on buying a cat delete pipe for the factory manifold and mufflers for my track car with no luck. I have a C5 Z06 that is a road race only, non street legal car. I want to get it dynoed to make it run slightly rich/ lean, engine survival and a bit of mid range torque is the priority not max power. The cats contribute to back pressure and heat. I cannot afford the cost or install labor to install long tube headers nor can I do it myself with my lack of garage space/ lift. I need input on O2 simulator or tune to eliminate the need for the rear O2 sensors. The threads that I have read on this topic all end up with people chiming in on the legality of the cat delete, recommending long tube system, insisting that cats do not reduce power etc. The cats are not desirable on a track car running at high RPM for 30 minutes at a time. Does any one have advice on where I can buy a non cat pipe to go between the stock manifold and muffler? Thanks!

Just find a local muffler shop that will fabricate for you.

and you can have the O2 sensors tuned out.

I run a C5Z on the track and do not run cats with the stock manifolds and Ti mufflers for a multitude of reasons.

Best option is to find another stock H pipe and have a shop weld in pipe to replace the cats. This is the best option and is cheap and effective. For the rear O2's I run plugs in the bungs and sims. Zero issues, no CEL. Might be hard to find sims these days so you can have them tuned out.

Check out the classifieds here with the heading "kooks catless xpipe with titanium mid section" and see if that provides anything you can use.
