The whole muffler piping is rusty as hell on my 99 GLE... i would like a deeper tone but i ale have a cali spec with 2 cats... anybody know know where i can find this? should i just keep my cats now and just buy the piping and muffler for now?

 

warpspeed y-pipe then either a stock replica exhaust which is like $200 or a performance exhaust which can be $700. Also check out mes exhaust and brm exhaust.
