Has anyone tried running duel pipes without a muffler? Or just small resonators? If so what were the effects on the engine? Did it cope with the change in pressure?

 

Someone did it already but with a Magnaflow muffler. I guess you can just remove the muffler and that'll give you the dual exhaust that you're looking for!

I removed the rear section of the exhaust for a few days and let it dump under the car. It was loud but not the loudest i've heard. probably because of the 4 cats on the car. low rpms it sounded bad *** like around 3k.
