I see they are on sale for 340 and was planning on doing something when the tranny goes in as my daughter is used to a loud deep exhaust from my TVR. How loud is it for those that have it? Will it po the neighbors and cops or is it someone acceptable? How is it on the highway? Is it better just to take the current one to an exhaust shop and have something welded in? If so what are the recommendations to make it deeper, not ricey?
