The under tunnel exhaust is pretty much a MUST! Its keeps your air intake cold and free from ice build up.
The Timbersled skid does exactly what they said it would, I wouldn't trade it for anything! ...and the gytr front shocks are just unreal, They're just such an improvement over stock, you can't even compare.
Unfortunately, after the mis-hap last week, I think I'm gonna be taking some time off from sledding for a while...... This sled might be for sale.
