I have had some rust issues on my exhaust and havent gotten around to fixing them for a while. My muffler fell off and my first cat on the passenger side broke off at the pipe. I dont really want to pour thousands of dollars into this. I was wondering the consequences of running straight pipes into a muffler with no cats. Will this decrease gas mileage, and bog down the truck even more with no backpressure?

 

I think you will fail inspection, unless you know someone.

I doubt you will notice a difference in power or MPG's. As long as you keep the same pipe length as before the back pressure difference will be minimal

 

i just passed my inspection with no muffler and the cat hanging half way off, i thought they were joking. so i have two years till the next one comes. i was thinking ill probably just keep the same size pipes on like you were saying... thanks for the reply!

Haha yeah I read through your thread about it.... I figure anything is better than a leak right under the cab

 

I'd put another cat back on.
