Dumping exhaust down under the car

I've been running mine that way since last summer. No regrets so far.
With a 5.9 Magnum, Doug's headers, 2.5" pipes and Jones Maxflow, the car is NOT loud. You guys with high compression will likely hear more of a noise difference in the cabin than I do.

Cutting the pipes did shave a not-insignificant amount of weight off of the car though. The pipes are hanging on the wall in the garage. I'll need to weigh them but I'd have to guess that it's 15lbs or so of dead weight off the car. :)

Sitting in traffic, the fumes are more noticeable than with the proper exit location. It's not a serious problem, IMO.
