Are you going with short tube or long tube headers? To be honest, you might as well get the LTs. The amount of work and time to install either will be the same. And both will need a tune. And both will void your warranty. So you might as well get the LTs. There are several different brands that sell the headers with HF cats/catless extensions. Shop around. Ebay, Amazon, and check with vendors. You can get some killer deals if you shop around. If you can hold out, you also might wanna wait until Black Friday!!
