Dual motoGP exhaust on hawk
What you guys think about this? Would it give the right amount of back pressure? Its baffled.. Thinking about putting my TBR on for sale..I kinda dig the straight pipe sound..
What I'm thinking about doing is use these as baffle and put more piping on it going under the tail.. Sound good? some jetting would do?

I just cut off the pipe to a stock exhaust from a i think an r-6 and the pipe is baffle so that will be my baffle and I will pay a visit to a muffler shop sometime this week... I always wear helmet.. sucks to be a harley dude with no helmet looking cool beside me.. will let you guys know how it goes with its done.. Oh yea just to tell you guys straight pipe is not good ( dont do it), I know some of you out there been searching I did my search already and I rode the bike today with straight pipe, very poor low end response and the high end is extremely flat.. hopefully with this baffle in there it would give enough back pressure.. I will be the pig on this one..

I ran open pipes on mine for a while (basically open - made a sort of DIY restricter to add some pressure). People behind me complained about how loud it was, although they admitted that it sounded amazing. Neighbors all hated me when I got up and went to work at 5:30 in the morning, but I must admit, as loud as it was to everyone else, it wasn't that loud to me going down the road. I do wear a helmet, and I could hear it, but it wasn't bad. Poor guys behind me though...

On my Hawt GT, which is a 2 into 1, I went to NAPA and bought a 7 degree angled exhaust connector which is about 12" long with a 7 degree bend in it for $6.00. I attached that to a SuperTrapp 10" SC Elite Universal muffler, which attached to the 2 into 1 collector located under the bike, like the SH sort of.

They have many to choose from. It looked really cool. I got the idea from the HawkGT forum. Sorry, no photos, but you get the idea.

It's decisions like this that could eventually affect all of us in the end. New noise pollution laws are hard to enforce now, but I'm sure with the ever growing popularity of putting straight pipes on your p.o.s. hog could give local authorities the leverage they need to invest in some decibel measuring equipment. I'm all about motorcyclist's freedoms, (no helmet laws, etc..) but living in downtown Prescott has made me a strong opponent to straight pipes. When the bars let out at 1am all you can hear is the roar of a bunch of HD **** leaving for the next 30-60 min. Whats wrong with with the TBR pipes you have now? I know that they're not exactly quiet, but I'm sure it's a lot more pleasant to listen to than your alternative. Myabe I'm just getting old, but it sure seems to me that loud pipes say "look at me, I need attention"

I got no neighbor I live in the country..TBR baffle is knocked off.. Plan is still on hold.. Still pretty much deciding if i'ma keep the rc51 fairing or not.. I have to open my TBR to fix it. Don't need attention as you can tell i live in the country.. thought it sound cool.. I did put that baffle on there to see how it sound.. it sound pretty much like the TBR but with less weight.. not too loud.. Thanks for everyone comments I really needed it.. cause cutting this I can't go back since i'ma cutting where the Y is at.. so yea...
We'll see

I like a nice sounding bike as much as the next guy but please don't go making it all crazy loud. There's a couple of guys with 600's on my local forum that I ride with occasionally and their bikes are downright irresponsibly loud. Without ear plugs you cannot stand to ride next to or close behind them for more than a few minutes. And obnoxious even at idle.
Definatley not good for the sport. Not much different than hanging wheelies in traffic or other squidly behavior. Just gonna make the public hate us motorcyclists.
I got to witness one of these jackasses dyno their bike too. The noise was definatley impressive, but highly unnecessary. He even brought a decibel meter cause he just had to know how loud it was. Form about 10 or 15 feet behind it registered 158 db. This thing was excruciatingly loud at 15,000 or more rpm!
And it was running so lean that it boiled over all over the dyno. He about **** his pants thinking a rod went or something else catastrophic. That was my first thought too. Then the smell of engine ice filled the room.
