I'm considering doing a similar mod to my stock exhaust also. I'd like to know what I'm drilling into before I start. So anyone care to give a more detailed description on how these pipes are constructed internally. Here's what I think know from reading various posts. There are 4 baffles in the pipes. Start by cutting out the rear most baffle and go from there. It's obvious to me that the rear baffle is welded in and I'm going to cut it using the hole saw method. How are the remaining baffles held in the pipe? How far are the baffles spaced from each other? Is here 1 or 2 plates holding each baffle? Any info would be great and if anyone cares to post a diagram of the construction, even better! Thanks for your help.
