I have an 88 f250 351 Windsor, currently have cat to a glass pak single pipe, sounds really bad and hanging down just looks like crap. I want it to sound good but don't have a ton of money to spend. Any recommendations?
I feel your pain.
On my 83 302, several years ago, I put a Walker Hemi Turbo muffler 2.5" SISO and had it exit before the rear passenger wheel. It sounded great. I have used the same muffler on a single exhaust on a couple of GM and Ford V8s and they all sounded good and the muffler was cheap. On my 350 sbc Suburban I did use the 3" model and had it exit all the way back.
Fortunately the Windsor sounds good with almost any low flow muffler. Check youtube for sound clips.
