slip on performance exhaust?

[jdman]

does anyone have one on their 825? how much louder is it? does it help performance?

I don't. I wanna keep mine stealth.:hde:

I went to the dealer they had one there with the performance exhaust from JD. It doesn't sound much different at all to be honest. Not worth the money IMO.

I have one on mine. As for the performance and the loudness I don't have anything to compare it to. My dad is getting himself a 825I without the muffler and then I will have something to compare it to. I love the sound of mine. Will post back when my dad get his and I am able to compare them side by side.

I installed a silent rider exhaust on my 825i helped quite a bit on noisey exhaust but now my muffler is burning out I'm going to install a flow master that is approx. the same dimension as the stock , I will let you know how that works out as far as performance and noise

[campoman]

flow master was to noisey , I'm still working on a exhaust system that works for performance and is somewhat quiet
