You M&k looks great, how's the sound? I currently have very old "thermal reactors" that do a great job of slowing the car down, so I want to put a new exhaust system on my 76 911S. I am between a Fabspeed heat exchangers and exhaust ($2,600.) that can be sent in a week, or SSI heat Exch. w/ an M&K exhaust ($1,600) and is back ordered for 4-6 weeks. Is the Fabspeed worth $1K more than the other? Which will give my 2.7 better performance? The Fabspeed only comes in duel out, how much of a pain is cutting a hole in the rear?

Thanks in advance,
John M.
