I've had exhaust drone since I had my custom exhaust built in October. Like many of us, I turned a deaf ear to it most of the time. It was 'other half' who prodded me into getting it 'fixed'. Sooooooo a buddy of mine from the local MB dealer referred me to a very good very COOL local shop that does lots of custom work. ("antique" cars, trucks, Off road Vehicles, Dune Buggys, etc) They are the polar opposite of places like Meineke muffler.

Long story short, Joe the owner looks under my car, grimaces at the "quality" of the previous work. He says 'for $250.00 we'll chop everything off from behind the (front) Cats, build in a crossover pipe and re-weld it directly to the Magnaflow mufflers'

I agreed, and they did a superb job! Nice clean SS tubes from my cats, X'ed Over then up close to the body and into the Magnaflow mufflers. A real work of art! No wonder it took them 4 hours! :-) Worth every penny!

Now I just need to find replacement gaskets for where the exhaust headers go into the CATs. I think mine are shot. Leaking badly on the drivers side again. The local parts house guys look at me like I'm from mars when I ask for them.

So in short, yes, the crossover pipes make a world of difference.
