Im gonna be purchasing magna duals si/do Part#15749 for my 2000 5.4. How loud is this magna...I know if you step on the peddle hard it will be real loud. But if im driving normaly, is it still going to be loud or will it be quiet...say below 3000 rpm. And will it be loud inside the cab when all the windows are close..I have heard that it is real loud in the cab and you practically have to scream to make a conversation. Please let me know if all this is true or not so I can convince my wife into buying one. She is complaining about the potiential loudness and would be embarass to drive my truck. Oh yeah..Can I get a Ticket for having exhaust too loud with magnaflow?
