I haven't heard their axlebacks, but you MUST get their O/R H pipe from Brenspeed. Pypes only sells it through Brenspeed. It will only enhance your sound, and give it a mean growl.
dont waste your money on SLP's, just find a good muffler shop,pay the 125 bucks and have some replacemevt pipes made for A LOT less..............Sounds NASTY!!!!!!!!!!!
I see a lot of recommendations for off-road midpipes, and that is fine. I have to pass inspection (one of only three counties in IN), so I had to keep my cats. I went with the MAC Prochamber that keeps the factory cats. It is F'n awesome, and it fit great. http://www.macperformance.com/store/product1.cfm?SID=3&Product_ID=1216
