Its a proven fact, the best exhaust manifold for the 16V in stock trim, aka no cams etc, is the stock manifold.

Wheel power yes!! Having cams and shit doesnt justify it as you pointed out?? Are you bi-polar??

Cool but old mani has a leak, between mani and downpipe, and want to keep low down power, I believe that the 20v is better desgined for our motors, so looking to add that, also its just a few mm bigger then stock, changing it also due to a few mods like increase compression and 57mm exhaust and also after market ecu, cold air intake, sooo yes stock mani is good up to 160hp as I read on the net, but if I have something that's better designed and developed then stock shouldn't I use it? Also in terms of after market I think they sick with a viper at 2k and sooo on, maybe over time I will change the down pipe to duel 50mm and the exhaust to 57mm into 63mm but that's when I have more work on the motor

With the 20v .. I made more power with the stock branch! i lost 8wbhp with a after market branch! I had cams coupled with head work and compression! Odd but thats what happen in my case.. You asked for advice.. in our opinion we rekon stick with the stock branch.. if it has a leak and u want to go this 20v route u should will be nice to see what happens.. then we will know for sure if its better or worse! I always thought 16v has bigger ports than 20v the exhaust ports i know for sure are bigger!!

@rxi bud I have a spare 16v head here, that's how I meassured things, but remember I have the ser3 small port head not ther big port t-vis head, maybe that's why u think its bigger then the 20v, my ser3 ports are small even on the branch, the 20v mani had bigger ports

Yes will fit and give results
