Just bought a new '08 S last month; getting back to riding after too long an absence. I was looking for a deep sound without being too loud and decided on the Roadhouse Dooleys. I installed myself (not exactly easy, especially the crossover pipe fitting, but very doable with time and patience). They were EXACTLY what I was looking for in terms of look and sound.
I also installed a Baron's big air kit at the same time. I was definitely getting popping on de-cel after installing the pipes and
BAK. Last night I installed an
AIS removal kit and it absolutely removed the popping. The bike now runs perfect as far as I'm concerned; no loss of power or any other funkiness. I may have even gotten a bit of power gain, but this is just a "seat of the pants" observation. I have no PC or other power related mod's installed.
I ordered the Dooley's from Phat Performance Parts(lowest $$ I could find when looking) in April, I originally ordered slash-cuts, but they were on backorder with no hard-date. I called them and asked if they had the taper tips instead, they said they could ship them right away and would be happy to modify the order. I believe I got the pipes within three days of that call. I would have been happy with slash-cuts, but I find that I really like the way the tapers look on this bike.
