NEILX5 0 Posted August 23, 2006 Report Share Posted August 23, 2006 Hi Guys, I thought aftermarket exhausts should be the same bore diameter as the manufacturer? I was thinking about getting a Milltek but the bore is smaller, now im swaying to a Jetex as the bore is the same 2.5inch.How important is this?CheersNeil Link to post Share on other sites
jaysVR6 2 Posted August 24, 2006 Report Share Posted August 24, 2006 Any bigget than 2.5 inch on a VR and you will start to loose torque. Don't go any bigger. Link to post Share on other sites

Milltek is the same as stock but more free flowing. Jetex are bigger than stock bore at 2.5" and are good if you plan on going supercharged in the future.I've got a Milltek... you won't be disappointed. But there are quite a few others out there that are very good too. Link to post Share on other sites
