I know I'm going to get told to go long tube but I have shorties with magnaflow high flow cats and bassani true dual and the car has a great power band for just cruising around. One of my cats has had something come loose on the inside and rattles. It drives me crazy and I could put the factory cats but why not just delete them and let the gas smell **** the people off behind me?

big hammer

Any muffler shop could delete them.

Stainless Works has a catless midpipe. Has been working great for me.

Cambo3, while this is the external engine section, exhaust issues which are more vehicle related than engine are pretty common here.

Just let us know what vehicle you're working on.

ASSUMING you're working on a 4th gen F-body, Dynomax makes a cat-less pipe kit that goes to the stock manifold setup. I believe this will pipe up to shorty headers.
