What is the purpose of an exhuast ground? I noticed the one on my Nissan Titan is broken and hanging down. I don't notice anything differant though driving it.
their is a major problem with my bmw 1997 540i exhsut and catylic system.
i am wondering where can i get a new ehsust system or a new catylic converter i would like it to be a different company which will make it sound better and give it more horse power
i can find anything for the 540i 97...
