im actually contemplating leaving it long.... i talked to a guy from a local shop today and i havent completely decided against cutting it down but im considering
look for a mounting bracket of some kind its ok of the ground is longer than a foot if you dont have any places that close you just want it as close as possible
ok well the bolt i found thats connected to the headers from there to were i would ground it is like maybe a foot.
thats too close to the exhaust id be afraid it would melt
when you arent in boost turbos atomize the air which creates a more dense charge of air entering the engine allowing fuel to burn more efficiently so yes you will see better mileage but that is only if you can resist keeping your foot out of it
