What would a test pipe do for me? I feel like my cat is slowing me down. Anyone?

A very large carsound cat will have enough surface area to pass emissions (in most states) and still flow good enough for your setup. Plus it won't smell. Just an idea. Either way, don't expect more than a couple of horses if you have a 2.25 collector/exhaust setup.

 

I gutted my cat today, cleaned it out real nice. I felt a soild gain actaully up top.
