If you have been reading my past posts, i had a few questions on installing an airfilter for a 98 306 Xsi. Well i just installed one and it sounds great but i seem to have lost some bottem end torque. I made a new induction hose to fit the filter (a simota filter) and its a 3 inch straight pipe. There is a 1/2 inch outlet pipe that connects to a hose that goes back into the engine. The inside diameter of this outlet pipe is smaller than the original one so could this be effecting the power? or did peugeot make the original induction hose an S shape for a reason? any advice is greatly appreciated
