Hey guys. I was wondering what the difference is between the catalytic converter, and the muffler on the Z. I have a 2006 Touring and heard that by removing the muffler (catalytic converter?) it would sound better (opinion). Anyway...how would i go about removing it..do i need to buy/have anything in particular.

If you remove the catalytic converters and keep the stock muffler, you will have a more aggressive sound while keeping the stock tone.

The muffler is the thing under the back bumper with tailpipes sticking out of it. The catalytic converters come down off the headers at the beginning (front) of the exhaust system.

edit - oh yeah, I guess that thing in the middle is a muffler too.

Put the Z on a lift and have a mechanic point out the parts of the exhaust system. That way you can ask informed questions.

I suggest taking a few minutes and simply look up all those terms on Wikipedia. You have some large holes in your understanding that you can easily and quickly fill. Once you have a basic idea of what the various components of an exhaust system are, then you can start to formulate questions that will give you the information you need.

in a nutshell

- Catalytic converters burn unwanted gases, make the exhaust more environmentally friendly. They are also a bottleneck for exhaust gases, since the exhaust gases must pass through a metallic/ceramic core. Simultaneously they also act as "resonator", although not quite, but they do assist in decreasing the sound of the exhaust.

-Mufflers are primarily for controlling the sound of the exhaust system. The exhaust gases are strategically scavenged inside the muffler to reduce exhaust sound.

This is very helpful. So what would be the best to remove and get louder, and how would i go about doing it...this is aimed more at people who have personally removed one of these. Thanks again!!!

Generally members are looking for performance not noise. Cutting and piecing together the OEM exhaust is ghetto. Shop for a cat back exhaust.

I am by no means a ricer and dont want to just make my **** annoying and obnoxious just by taking off cats and getting some chrome at my local walmart lol...as you all know money is tight, and i dont have the bank for a brand new bassani...so i just wanted a quick and easy way to a more aggressive exhaust.

quick and easy way -----> remove your cats and replace them with test pipes. Your exhaust will be louder, slightly raspy, slightly smelly, and you'll also get highway drone.

replace cats with test pipes, and get a good aftermarket exhaust...that will get you the noise you are looking for...also it will be a smidge louder at WOT too if you add in a CAI
