I am on the lookout for a almost new MCS as i cannot get a new one till October, i want to aquire a new air filter and exhaust system, but as i am reletivley new to the MCS i am not sure which combination to go for.
Do i go for the full system from the manifold back or just a rear box?
I have read this site from front to back (top site) and have seen some good reports on the products.
Can anyone shed any light on my potential purchase,
