can i expect to notice any difference once i install my crawford cats? currently i have a crawford plenum, borla exhaust, grounding wires, and a injen intake.

 

Yep, you will. I have the plenum, "Z" tube, POPCharger, fabricated dual exhaust system, and grounding wires. I've had my cats for about a month. You'll notice a growl in you exhaust. More Power and not much louder idle note. At WOT, however, the exhaust roars, and the car takes off. The Crawfords are also very well made, and fit perfectly. You'll luv 'em.

free-flowing cats will have less back pressure and therefore a noticable loss in torque. Can someone confirm or rebutt?
