I noticed your exhaust mod on your thunder cat did it help the back pressure.Also what does it sound like.</end quote></div>

Sounds about twice as loud and sounds more like a road bike, Ill post a vid once I get it back from the shop, before I did my mod, I asked a guy how it sounded and he explained as sounding like flow masters on a GT mustang. Yes it helps with the back pressure, these pipes are very restrictive to the 650 and 700 and now they are on the T-Cat, with this mod it ads 6hp to the rear wheels, and you feel it, Thats one hp less than the Black Magic slip on, not bad for a free mod. Just take the spark arrestor out and ride it around, thats all im doing till I get my mod done.
