The typical exhaust upgrade (as I understand it) for our Opels is:
1) 2" pipe at the point head pipe goes from two pipes to one (approximately under the passenger side floorpan)
2) suitable muffler/resonator near that point
3) 2 1/2" bent pipe going over the rear axle
4) 2" into a rear muffler and out into a tail pipe
I recently asked the numbskulls at Midas to do this and when i went to pick up my Ascona the guy said. "Oh we used 2 1/4" all the way it won't make any difference"..........is he correct?????
