Just for sound, i know it won't do much in terms of HP on a stock 318. I plan on making it dual exhaust at the very least. If it's a pain, i don't mind keeping the stock manifolds and just going dual exhaust.
I had duals made, and it is a very tight bend on passenger side over the oil filter, and over the steering. The worthless tit that did mine didn't do a good bend and it hit the idler arm on the steering linkage (the arm that is parallel to pitman arm). Thus ruining that piece, when I replaced it with a lil beefier one it hit so bad the car would not steer. So have another shop try to fix the exhuast right, or a pair of $150 headers... was a no brainer for me. Yes the steering has to run thru the headers, and yes they will bottom out if you don't raise the front end a bit. As for crushed flat... I live in an area whit tremedous frost heaves, and haven't had that problem. Besides, how do all those lowered cars get around without dragging something.? And I can buy a lot of inexpensive headers for the prive of the "good ones". My car is a driver, not a show car.
