It's been awhile since I been on this forum. My old 8 crashed.
Good news is I bought another one.

Looking for best suggestion for Catback System with a reasonable price. Under $600 if possible. Don't be a pen is.


Also, if possible. Please link site to me.

 

There is a large bar up top that has a search box, I suggest you try that first and then come back with any questions. But with a $600.00 limit your options are very limited.
