hello im putting a straight pipe exhaust on my car and was wandering if 2.5 inch tubing would be too big on a stock engine? a local exhaust shop was saying 3 inch tubing would be standard but the stock pipe looks like 2 inch if that. so my question is what size would you use? thanks

 

dont straight pipe it.

This is true, as you lose a bit of torque when you do increase the diameter of the pipes. The actual stock diameter of stock pipes is 1.75", unless you have a V6, of course.

 

Im going to suggests test pipe over a straight pipe. 70mm exhaust or 3 inch if thats all you can get prepare for lower gas mileage.

 

Good luck getting pulled over. I drove ONE mile straight piped, from the high school metal lab to the local iron works to have my new Megan muffler welded on to my 2.5" piping. I was "disturbing" the peace, I went and explaned what was going on and he let me go of course.

 

sorry but its the little 2.2...why not go straight pipe? im wanting something real raspy any ideas?

 

right now the exhaust is cut after the resonator been like that for about a year now and no disturbance problems from the law yet

 

how is this?
