Hey guys, I have found so much help here from you guys and was wondering if you could give me some advice on something I want to do. I want to replace my muffler with a performance grade part. It is all rusted back there and the crome tips are falling off because the bolt rusted. I'm new to the whole car part replacing world and think the muffler would be a good place to start. I dont think I need to replace the catalytic converter and before, just the back muffler. How would I go about this? I also dont want a showy loud muffler, I want a quite but performance sound, where would I go to get one of these and make sure it fit? thanks guys.

Exhaust work is a pretty specialized business. It requires tools and supplies sometimes not even found in most repair shops. Chances are you will need both a welder and a torch and possible even a pipe e bender. You will also find that most of these exhaust shops work pretty cheap. That's the way I would go with it.

I have been looking around the internet and have found this bad boy http://www.autoanything.com/....aspx#customerReview What do you guys think .The reviews said install was short...no welding? Does cat-back mean catolytic converter back? I assume, so does that mean I just bolt to the catalytic convertor and no welding? Thanks guys.

They can claim anything they like. That doesn't always make it true. They don't know what the condition of your system is or what welding has already been done to it. There isn't much you can do with exhaust that doesn't require at least a torch. Old pipes don't just slide off, especially if they have been clamped and crimped. Sometimes you have to make sections of pipe to replace damaged or welded parts.
