I have a 96 GLE that needs a new exhaust system b/c it is beginning to rust. I did some research and came up with this exhaust system for my max: warpspeed y-pipe, warpspeed catalytic converter, and Courtesy Nissan B-pipe. Any recommendations for a muffler? I like the look of a 4" tip and prefer a nice deep tone, "not ricey" as everyone puts it.

BTW, I noticed warpspeed sells two types of catalytic converters: metallic substrate and carsound.

They claim the metalic substrate has better flow than the Random Technology catalytic converter. Is the metalic substrate worth $75 more?

Thanks for any feedback...
