I am getting ready to put on the new exhaust and thought I would ask for any helpful tips. I am not welding, and I am going with 2.5 dual compared to the 2 single it came with. I will check back because I know someone you will give me what I need to do this right. Thanks

Hard to know without more info about the car. You might consider adding some details in your sig about your car. 2 1/2 can be a little large for smaller displacement more stock type motors. Like carbs, 'big is not always better'. There is advantage to smaller pipes as it tends to have a higher velocity so it help 'pull' exhaust from the cyl when the valves open. Too small isn't good either though...

I have yet to see a 2.5 inch system that will bolt in without significant modification. Will e is right, there is no need for a 2.5 system on the set up you have. Chuck
well the only reason I got it because it was the same price as the 2 1/4, so I figured why not
