I was wondering what was out there for my cat. and what in house mods have been done. I think for now im removing the intake trackt and hooking the maf almost directly to the throttle body with a hood scoop feeding in and removing the exehaust system for header back straight pipes to resonators dumping just before the tires. I mean what info is out there... also my front end is eating dirt Stability controal fail is on... ITs a 97 XK8

 

What exactly are you attempting to accomplish? The reason for the plenum length and shape is to accelerate the air to a certain speed as it enters the motor. That includes the duct from the air cleaner box to the throttle body.

Did you search the forum for information on available exhaust system modifications? Bear in mind that they can also affect emissions and, depending on where the vehicle is operated, may cause the vehicle to fail any emissions test. AJ6 Engineering in England have developed exhaust systems specifically for these vehicles: HIGH QUALITY XK8/XJ8 EXHAUST SYSTEMS from AJ6 ENGINEERING / AJ6 Engineering.
