So far I have only been able to update the exhaust with a Flowmaster muffler, Walker Dynomax Stainless tip, and custom piping from the cat. It has an amazing low tone and growl. She might not have a real deep bite but she has one hell of a mean bark. I have any plans on replacing the OE air box with K&N's aftermarket cold air box and plumbing. I'll post some pictures as soon as my lazy but washes and waxes it.
I came here looking for some inspiration but I do want to keep it pretty close to stock as I really like my 26 MPG.

Well they do become really big numbers as gas approaches $5.00 a gallon, just wish the gas tank was a little bigger then 17 gallons. Then again it costs me $68.00 to fill it up now so now that I've thought about it, 17 gallons is enough.
