So I know I'm new, so don't take this wrong....but that doesn't LOOK like the American Thunder NPP system that I've seen. ...and the way they've got it welded, how does it bypass the muffler? Does FM offer a muffler with an internal bypass?
EDIT.....OK, I see. That pic is the original FM muffler only system, no NPP. ....so how do you like the whole american thunder system?
