How good is the quality and DO they fit RH drive cars ? I took my inlet manifold off ported it a bit ,had it coated inside and painted black, looks real nice. I am getting 7.5 PSI back pressure at max power on my standard cat exhaust in good condition. So are planning to start looking at the exhaust side.
