As a birthday gift to myself, I had my local muffler shop remove my stock water heater (stock) muffler from my X, which just hit 1,000 miles, and I had a custom MagnaFlow exhaust installed. Wow!!! I am totally happy with the $175.00 that I spent and now the throttle and accelleration is superb. The X can breathe with my K&N air filter and now the engine back pressure is non-existent. Amazing what a difference! Just had to share.

Thanks for the info. Ive got a 2004 with 900 miles and I had an app. to put a new ex. system on but I backed out. The dealrship told me that It whould screw up my 02 sen. and the check engine light would stay on. Guess ill have to make another app. and get her done.

If there was no back pressure, your engine wouldn't run.

Sheeesssh.... well, I don't have the restricting back pressure now. It's nice to be able to stomp the accelerator without have to get a stiff hamstring.

incorrect.

Whaddya mean, I've seen engines run with straight pipes, no mufflers, exhaust right out of the headers.

whereabouts did you get it?

I replaced the stock muffler and got a Magnaflow 6" x 18" round muffler to replace it in the stock location. The muffler shop that I went to is called Lord's Mufflers on Peachtree Industrial Raod in Sugar Hill, GA. I could have gone with the 6" x 24" but I wanted to have growl. When I stomp on the gas at over 2,500 rpms, there is a nice growl, at cruise speeds of 2,000 rpms its as quiet as stock!
