Got an 87 Mustang GT. The catback system needs replacing. I'm gonna get some new mufflers, and my tailpipes are rusting right now. The mufflers can wait a little, but the pipes have gotta go soon. In the interest of money when replacing the catback system, is it even worthwhile to replace the tailpipes? Couldn't I potentially dump from the mufflers? Anybody want to fill me in on the benefits and/or cons of dumping from a muffler as opposed to tailpipes? I gotta get my pipes off now, and if I can avoid buying new ones that'd be great. What effect will it have on the tone of my exhaust?
