You should probably start looking through the exhaust catalogs online like I did to find resonators. I ended up with a decent list, but I was looking for long mufflers. Off the top, Magnaflow and Cherry Bomb/AP exhaust had some shorter cans. Magnaflow were available in stainless, iirc. Vibrant makes mufflers and resonators. The resonators are short. Put two on there, lol
