Thread: To Chip or performance exhaust system TD5 Auto

He has a manual though, with which you can avoid the worst of the noise, and doesnt often tow.

I agree with you that removing the muffler and running just straight pipe is a bad idea. It's droney, noisey and not pleasent - especially bad for the rear passengers. When I purchased my D2a the previous owner had removed it and left just pipe there.

Instead of having the restrictive factory muffler, have it removed and replaced with a straight through performance muffler in 2 1/2" size. This removes the drone and lowers the noise level to a much more tollerable level while still giving you most of the performance benefits of running a straight pipe.
While your there I'd also replace the two smaller resinators with straight through hot dogs that would flow better.
