[QUOTE="jimmyjamm, post: 1632729, member: 38515"] The bolts on that will help some (we aren't talking 100+ numbers, but small gains in the 10-30ish Hp & torque with each add) are: Intake: -larger intake filter to allow for proper amounts of air flow with less restriction-if getting an intake kit usually they come with a more efficient filter to intake Y pipe for better flow, reduced intake velocities and additional intake runner volume help with both throttle response and top end power; -Intake tubes, both hot side and cool side, with increased boost you will get increased intake velocities that cause more friction losses in the intake, also, more intake volume allows for reduced pressure fluctuations from each intake pulse. Exhaust: -turbo flange adapters, these will increase efficiency into downtubes and reduce back pressure and heat in the turbo-helps with durability; -downtubes, common upgrade on any turbo vehicle are larger and mandrel bent downtubes, allows for faster spool and more volume with lower exhaust gas velocities reduce friction and heat buildup that robs power at higher rpms (keep the heat in the main stream of exhaust gas flow and that aids in ability for the exhaust gases to flow more efficiently); -eliminate the exhaust resonator, as it reduces the exhaust pipe size from 3" to 2.75" that causes restriction (the stock mufflers aren't awfully restrictive, so those can stay); -change out the tailpipes from the muffler back with mandrel bent tailpipes, the OE pipes are 3" but with all of the conventional bends they add a lot of restriction from the inefficient bends with changes in internal pipe diameter and shape causing pressure fluctuations and friction losses.
