I have a Hagn big 16G on my car now. I also have a hahn 3" o2/downpipe combo with a 3" Thermal. I have really bad creep problems, and have been told to port the o2 housing and do the 34mm flapper mod. I also have a spare Tial 38mm wastgate laying around, and was wondering if it would be better to use that to get rid of creep. Can I somehow work that onto my stock exhaust manifold, or do I have to buy an aftermaket mani? Thanks
