I want to eliminate my cat since my 83 pickup wont pass smog due to my weber carb and have an exhaust leak on the cat so I wanted to run 2 1/4 inch pipe with the stock muffler its a walker I believe. Any advise is appreciated thanx
Thanx for the input guys and my truck didnt pass so my dad paid the guy to pass it so dont have to worry about it until I need to renew it but how can I tune the carb?
I have my Weber tuned at Ace Fuel Systems. They are located in Santa Clara which is really far from you, but you should be able to locate a carb shop in your area. I've gone to them once for a "pre-smog" in the past and they get me all dialed in before I get on the dyno for the Test Only. Rick
I'm assuming they rejet the carbs to dial in the perfect fuel/air ratio so your truck doesn't run rich or lean. There is a guy up here in spokane that is like one of the top ten carb guys around. Not even just the area. You would have to send it to him but i'm guessing there is a shop around area that can help you out. Other than that yeah i would agree with what everyone said so far. I would just have the exhaust done right the first time instead of spending the money to have it done right to pass emissions the next time you have to go in. No sense in spending more money than needed just for a year or two of the type of exhaust you want.
You can also get a larger cat if the stock one is too restrictive. Might take more research considering you're in california and would have to get a california-style cat with whatever bs the state wants on it, possibly off a different vehicle. Probably won't be cheap either.
