I have been running an ECP intake for years now with no issues. Manifold and Y pipe cracked at the flanges... so since I had the Big Blue Machine apart I figured I would get an after market exhaust. Why not right? Just wondering what the jetting should be. The kit came with 165 mains and I noticed that many others where running 165 with intake and exhaust. However, some are running 170 even 175 mains. I mostly run trails 0-2,500ft max elevation, but they are on the Canadian super highways. On days where the temps are 20-30 degrees she's is fat. Are the the 165 mains enough or should I be worried? Any help would be appreciated. Thanks.
