Another cat/muffler question :)
My '83 12A still has the original catalytic converter. It's starting to get a rust hole in it. In addition, the insides have rusted/burned out of the oiginal muffler. I'm thinking of getting the Bonez cat replacement pipe and Borla Pro-XS muffler (least $ I can spend, I think). Any opinions of how loud this would be? Also, could I just leave the tube form the air pump to the cat open or would I need to clamp it or remove the air pump altogether? I'm not ready to do the rat's nest removal yet...
Alternative would be Bonez high flow cat and muffler or Racing Beat muffler.
BTW, no smog checking here in NC, but we're supposed to have all original smog equipment. For that reason I'm hesitant to go with a full header, etc.
Thanks! - David

Well, the full header they will never notice unless the police look under your hood. The straight pipe will be louder, even a presilencer will be louder than the stock cat setup. I'm running the racing beat setup from front to rear, love the way it sounds, but it is louder than most cars on the road even with the presilencer and muffler.
Be forwarned most after market headers will require the removal and blocking off of the ACV on the side of the engine, so you might end up removing the ratsnest anyway ( fun and easy) If you do go that route, I've got an extra set of block off plates I do not need from racing beat.
