Hey Rick, glad you've joined the forum. I trust the 850 is going well. Pop some pics up when you get a chance.
Vee_Que;22066 wroteBest advice I'd have is go to a good exhaust shop and have it made up.
Going with a good custom built exhaust system or DP is the best way to get what you want and hopefully not paying the earth.
A decent exhaust place who is interested in the work is the best play and fitment will always be better than any of the kit DPs or exhaust systems you may buy.
The difficulty is finding someone reasonably close who is either willing to do it or does good work.
Some places are happy to push 5 commodore exhaust systems in a day but might be reluctant to spend the same amount of time and only get a single system done on something a bit out of the ordinary for them.
