Default Re: 3" straight pipe exhaust - DRTDEVL

If anyone cares...

A recent freeway trip confirms that the 2004 with 2 1/2" glasspack still has an edge over the 2006 with intact OEM muffler system when it comes to initial acceleration. I still mostly drive the 2004 so this is the first drive with the 2006 since the 2004 glasspack install.

Noise level difference 2004 vs 2006 isn't noticeable to my old ears.
