Has anyone heard of or have the mbrp pipe? It is a new product for them and from what I understand it is suppose to provide good performance and nice low dcb sound. They told me around 96 dcb for the slip on and approx. 4-5 hp gain w/ jetting. I would recomend that they should add a sound file to thier web and a dyno test after mods to show the X-tra hp gains. With a price tag of $260. for the slip on and $160 for the header system , I'am a somewhat hesitant about ordering one without confirmation of thier claims.. Thier web site is @ http://www.mbrp.com/MBRP%20B/index_B.html If anyone is interested in checking them out. I also just ordered wheel spacers from http://www.sand-sport.com/catalog/netcat.htm and will post a message with my take on them when i get a chance to check them out...
