ORB 227 1 Cars Posted October 9, 2006 OK, So I am just about to start putting twin 40's on my H reg 1.6 GTi The car is fitted as we speak with a full Mongoose Stainless Steel 3 inch system would it be wise to keep the Goose exhaust, or put on the original one i have sitting in a box at work? I am thinking to make it breathe at its best with the carbs? your thoughts please? Share this post Link to post Share on other sites
sonofsam 5 Posted October 10, 2006 Is that 3" all the way down the exhaust-sounds a bit big to me. Bit of a ball ache , but you could always swap them over see wich one you prefer:) Share this post Link to post Share on other sites
