It might be a long wait. I actually like the sound of my stock exhaust with cats. (catless DPs)

My next big spend is an LSD & Subs. I'm just so tired of the @ end of the car floating all over the road. I think a set of H&R springs are in order as well.

Wasn't the rasp that I didn't like, it was the drone at highway speed I couldn't live with. Jump to the 10m mark.

I didn't know you had an HPF system once? Cool.

I really just tried the pipe out to see if I liked it.. This was the prototype Chris just received and wanted to shoot a video with stock DPs and then catless DPs... I think that pipe ended up on Eric's car. I wanted to dyno with it as well, but they screwed around and took their sweet time so I actually ran out of time and didn't get chance to see what she made in comp to the stock exhaust... To be honest, the drone was more than I could handle.

The only HPF part I have is the 7" FMIC which I love... Actually ran into Chris at PIR Late Night Drags this past Friday night. He stopped and hung out for a few minutes which was cool. Marv85, CWarren, and ronin335xi were all there as well.
