I replaced mine with an "el cheapo" I'm not even sure what brand it is...... I'm sure it won't last forever.... but for the price, it cant be beat.
Regardless, I was VERY happy with the sound.
A word of warning.... I recently put a SHO shop offroad Y-Pipe on my car, and at cold engine there is an incredible amount of rasp!! After everything warms up.... the rasp is nearly gone...
If you intend to do a Y-Pipe, go with a better, turbo style muffler, or something people have done before and like.
I ran across the Y-pipe for a helluva deal....but now I'll be putting a different muffler in the place where the Res. was........
