Delete Muffler or keep.
Well right now as we speak you can barely tell i have a muffler and hardly see the tips of my exhaust since everything is black underneath the car. This is more for weight saving but i wanted to cut the exhaust system off and let it dump right before the axle. Im want to take off the exhaust cut out and just put a oval muffler or maybe a long resonator. Has anyone figured out how much the exhaust system weighs or how much weight i will save by cutting it before the axle. Will it also sound good by putting a muffler and just dumping it before the axle. I dont want to do true duals, dont want to get too expensive going this route. As far as power i dont think im gonna gain anything either way since my exhaust cut out is right before the axle and most of the exhaust exits through there anyway.1993 Z28 M6: K&N Intake, 52mm TB, TB Bypass, No Cats, Exhaust Cutout, Flowmaster Muffler, 3.90 Gears, 160 Thermo, Tune, BMR Springs, Bilstein Shocks, 3 Point SFC,s & MGW Shifter.

I don't know how heavy the exhaust is from the over axle pipe on back, but it's a nice chunk of weight (depending on how heavy the muffler is)! IMO, get a 3" in/out, 4"dia. bullet muffler, a good turn-down and a universal exhaust hanger.
Without any muffler it'll be loud all the time, so put a bullet muffler on there.

^^^ That looks really good, do you have any exhaust sound. Very clean job.

To the OP:
Take a look at this link. I posted a vid of my car and what it sounded like with open exhaust.
At first, I liked it. It was LOUD and I thought sounded good. As weeks turned into months, it got old and annoying quick. Every little thing I had in my car rattled, and I could not hear myself think. I grew to hate it. I now have my Flowmaster Super 40 welded back on and am happy with the way it sounds. Much quiter and has a better sounding, deeper tone.
