So what is the matter with the piece of wood and lump hammer method..
As you are upgrading your motor to somewhere around S spec I would think the 45mm part of your exhaust will be starting to restrict things, A full 50mm S system with open cams should be the way to go, any bigger and it will have to be specifically designed for the Bip engine to clear the 5ump which is already a major problem with the 50mm S system that I happen to run on my 998, even when I fitted the 54mm half system this pulled the modified front cylinder pipe hard up against the engine so it was soon returned to 50mm cans and crossover. I have trie various ECUs but can't say any of them have been perfect so a while back I purchased a DB tronics add on fuel trimmer and was going to fit it early in the new year but earlier this week I won a USB powercommander on Ebay so I will now be fitting that instead. Then I hope to have it on the Dyno to see what power my 998 Hybrid has.
