Exhaust System for Rotrex powered NA

Postby OVERDRAWN » Sun Apr 19, 2009 11:49 am

Hi I have an NA which has just had a Rotrex Supercharger fitted. My current exhaust, 4-2-1 extractors, 2 1/4 inch Magnaflow Cat with a 2 1/4 system. Is there any worthwhile HP @ Torque improvement going to a 2 1/2 inch system from the Cat back.
More air in,more air out ?.
Cheers
Steve

The system diameter you have at the moment will support more than enought horsepower. We have a MP62 running 277bhp with a stock 2001+ manifold/CAT/mid section and RB duals. With the Rotrex, power/boost should climb steadily, any irregularities in the figures will tell you if you have an issue. Get in on the dyno first!
