I was wondering if anyone with the two brothers exhaust has installed the M Series P1 Race Pipe PowerTip? It says that it adds HP. I was wondering if anyone has installed this?? If so did it make much of a difference?

Also has anyone installed the Q1 Quiet Core Insert?

I want it to sound nice and deep. However, I often ride in a pack and I don't want it to be annoying. One guy that rides with us has such a loud exhaust we make him ride last because you can't stand to be behind him. I want it to be deep but not annoying. I am curious but what is the decibel level of a stock on an 05? I hav decided to get the Two Brothers. Has anyone found any good deals for them online? I found a link that had the carbons for $900.00 with shipping.

 

I have have the 2 bros, but neither tip... I have rode with an 05 with the "power tip" and have mixe emotions about em. With them in you lose that bad *** growl of the pipes, but if you have a passenger you can hold a convo easier. I personally prefer the pipes without em, so does my friend unless he is going on a long road trip...

 

You should check out Akrapovic they have a great sound.

 

i agree, you should check out the Akrapovic exhaust. Expecially for the 05 636. I think it looks sweet. It looks almost identical to the stock exhuast, but will sound a helluva lot better im sure. its not street legal, so itll be good that it looks stock, that way you dont get messed with. here is the link: http://www.akrapovic-exhaust.com/mai...ts-catalog.htm. I was pretty fixed on getting the two brothers exhuast but not after seeing this. Like i said i cant find the price, but if i had to guess i would guess around $500, which is half the price of the two brothers. Now this is the exhuast that i am planning on getting. Once i pay off my ticket. daaamnit!

 

I found this Akrapovic slip on. Does anyone have a sound clip for it? How much HP does it add? I am assuming it works well with a Powercommander?
