Front Strut bar. $20.

I have a stainless steel sport muffler (Apexi?) that sounds pretty neat but I'm selling my car and want a stock sound. If you want to swap 4th gen mufflers with me, you're more than welcome to have it - as long as I can get yours off. Either way, you'll have a pretty cool sounding Maxima. And best of all... it's FREE. I spent close to $100 just customizing it to fit in December.
