power commander 5 with auto tune a must have!!! i just installed it and much better. pulls alot harder and no caugh off iddle since adding 6% fuel from stock map at 0% throttle from 1250 rpm to 2250 rpm. i am waiting for my GPR single side to arrive still. will remap and post afterwards.
I have been patiently waiting for all the news regarding this exhaust (weight loss, power, noise etc)...and nothing !!! What happended ?
You've read the other thread too? http://www.cafehusky.com/threads/g-p-r-motorcycle-exhausts-im-working-for-you.34373/page-7 You do save some weight, but you can't tell when your riding. You might get a slight power bump at low or mid-range but, again, it's hard to tell. The sound is much better than stock. A nice deep note when you're on the gas. It feels like I get a power boost - because I love the sound of the bike when the giving the throttle a twist - so I'm always on the gas when I can. I'm very happy with my single setup.
Thanks, Chuffa, interesting reading. I guess it's more down to sound and looks. Will have to decide after Xmas what to do.
I have weighed the stock mufflers (without catcon stuff) at 2.8Kg each. I also have a GPR Tri-oval muffler that weighs 2.2Kg. So assuming some weight saved in the link pipes (1Kg ??) and losing maybe 3.5Kg on the mufflers - total saving of 4.5Kg(+ or -). Doesn't sound like much until you hold a bag of potatos or similar weighing 5Kg.
Well I caved and ordered the dual pipe set up with no cat's. I have noticed the price seems to be climbing on these and didn't want to wait to see the price go up any more or be forced into the cat model.
