Hi Guys well my turn, I'm looking to change my pipes and get a set of Cobra Speedster Swept Exhausts. Now getting them may not be the problem as Metric Thunder in the states have them, tried here and they cost almost $400 dollars more. But my question to anyone who has upgraded there system, Do I need to change the air filter and if so to what type as I'm clueless, and why is that done?
Question 2 is do i need to buy a commander, to map the system ? and if so Why do I need to do this?
Any information will do please don't get to complicated/ Technical.
Looking forward to your replies and then I'll make more enquiries to purchase some in teh new year.
All the Best for Christmas.
Regards
Rick
