I've been reading some other threads on here saying that A-body headers tend to fit best on M-bodies; I was taking a look at the '88 5th Ave I'm going to buy and it might have just been my eyes but the passenger side inner fender looks quite a bit closer to the exhaust manifold than I remember on my Duster...? Since they are shorty headers (Hedman Tight Tubes) which exit down and end right at the oil pan rail I fab'd my own down pipes which snaked over the steering linkage in my Duster; shouldn't these also fit because there are no torsion bars to get in the way, or is the steering linkage in a different location than on A-bodies? Also I don't want to bother with doing a "clean" full exhaust with a Y and large single tailpipe I really want to make it a side-exit exhaust with the tips right in front of the rear wheels. Has anyone done this on their M-body? Due to emissions laws in CO I will need to run a cat on each side but those aren't too expensive nowadays and probably will work better than the horrible old triple-cat system these cars came with. I know I will need to block off the air injection holes in the heads as well since it has an air pump.
