New Exhuast Help

I just bought a '97 Z71 ext. cab short bed. One of the first things I want to do is an exhuast system. I would love headers but are not sure if they are street legal. I think but not sure that if I get cats with the headers then it is legal. If so I will go for the high-flow cats. but not sure about the other parts. I like Flowmaster but cannot find Headers for my truck. If anyone has a set up like this can you give me some pointers. Ididnt mention thisbut I also want it to be dual exuast out the back. Not a big fan of side exist. Thanks for the help.

If anyone does have a system like this could you give me some places to shop. Places that arent advertised everywhere that might have better prices.

Thank you.

Re: New Exhuast Help

First, please fill out your profile more. Knowing where you're from helps with stuff like this.

That being said...

Try JBA for headers. They claim 50 state street legal.

As far as true dual exhaust, and since we're still running street legal, some states like the wonderful California do not allow changeovers from single to dual; you'll need to check with the state you live in for laws.

Again in California, you're not supposed to change your catalyitic converter until it's either A> been through about 65,0000 miles (? might want to correct me on this) or B> been completely thrashed. But that's easy to fix. Just take a hammer to it! Then you can get a monolithic cat that works.

Summit still has good prices. Otherwise shops in your area might give you a break. After that you just need a good exhaust shop to help you along.

I do live in California but it is not registered to Ca. It is regestered in Ca. right now but will not be for long. I am in the military and will be moving to either N.C. or Il. at the begining of next year. I will risk driving around with something illegal in Ca. for now untill I get somewhere else.

Re: New Exhuast Help

You have duals.....just a dual inlet single outlet muffler

IMO you wont pick up much performance from a full exhaust set up on an otherwise stock truck. Sound yes. There just arnt many "bolt ons" that really make that much of a performance difference on a stock truck. Replacing your muffler with something else wont really give you much gains but it will make it sound better. That would be my advice unless you are going to dig into the motor. A cam and possibly a chip burnt to the cam specs is a good way to get some power fairly cheaply/easily.
