Collector extension question

ciara · 08-25-2002, 10:02 PM

I am putting 3 inch collector extensions 18 inches long on my 85 mustang with a 351w. Will it hurt if they are bent to clear the crossmember or do they have to be straight. Also what is a good muffler to use to quiet the car down alot. I am going to put them on while running the car at my house then take them off at the track. Car is way too loud with open headers in my neighbor hood.

If you have to put some bends in the tubing to get it to fit nice, no problem. Shouldn't hurt a thing... since you don't plan on running them at the track it doesn't matter.

Also a couple bends will quiet it down some. Speaking of which, a standard offset/offset 3" turbo muffler would make 'er quiet and they're cheap, a straight thru glasspack-type muffler would also quiet it down at idle and part throttle.... with some turn-downs/outs.
Yep... sounds good. Take 'em off and let 'er rip!
