Exactly.  Loss of back pressure results from larger diameter of piping which = less torque. _____________________________ *Quit Later (in reply to legionofone) Post #: 19

Just go as large as possible before you run into delamination (turbulence) of the air stream through the exhaust. _____________________________ CD5Tuner.com - 5th Generation Accord Online Community 94 Accord Mugen SiR Sports Sedan (in reply to trukid21) Post #: 23
