I guess you could say I took my first bombing step this past weekend. My 4" Jardine exhaust from Pinnacle Performance Products came on Friday. I thought this would be a fairly simple process to change out an exhaust system. WRONG! Word of advice to anyone wanting to do this on their own: GET A TOOL THAT WILL CUT YOUR STOCK EXHAUST EASILY!!! I ended up having to cut my stock pipes in three different places to get it out. The only tool I had was a hack saw. 8 hours later I finally was able to get the stock system out. The new exhaust system install was much smoother. No problems at all from the turbo output all the way back to the Magnaflow muffler provided. I had some trouble with the last piece that attached to the muffler exhaust that went over the rear axle. The mounting brackets provided utilized the stock hangers. Instructions could have been a little better. The price was great though (beat everyone else I could find by $100). See their ad in TDR issue #41 and ask for the special TDR member pricing.
