I run the 2Bro's full system too. I never tried the stock with the cork out. I never really had a chance too.
I do love the 2Bro's pipe and you are suppose to be able to buy a quiet insert for it that brings it down to 96db. I dont' know how bad that chokes it up though.
As for noise I think it's louder then stock with Baffle in, of course, but not ear piercing louder. I had a full yoshi on my YFZ and that thing hurt my ears. The 2Bro's pipe is loud enough that you know it's coming but not to loud to need ear plugs.
King, can I get a low down on those Cams? I have Crower cams in my 4Runner and they are excellent. Huge fan of there work, though they can be a bit slow sometimes. (I mean slow service)
Well BCGIrish, the crower cams im getting are apparently for the RMZ. I think thats what all these companies are doing, just converting the sprockets over to the LTR and using them. If you look at their site, it shows a gen1 and a gen2. I want the bigger duration cam to help improve the mid-top end a bit. I feel im going to have plenty of "down low" power with the HV porting and i feel i can take advantage of a longer duration cam with the porting.
Dan Crower, owner of Crower Cams, said he can build them in billet or weld and regring my stockers. I told him to do whats best and left it at that. I want reliability so that most important. I have a feeling im getting a billet set. It also appears that he is only considering doing the intake cam but he did ask to see the exhaust to see if we can improve upon it as well. Its definetly the intake that is a bit deficient on that machine.
I just want you guys that own the 2 bros pipe to know i wasnt dogging it, i was just questioning its full potential but you guys really seem to like it. It sure looks tight and clean. Im still lost on pipes. Im not going to try any pipe until i decide whether or not my franken pipe works or not. Im about to order a big fat reverse conicle air filter to go on the end of my trinity velocity adapter. With no air box and pipe crowing that area i can run what i want. Just flip that stock plastic heat shield upside down and i should be splash proof for the most part.
