Just like stock at idle, at 1500 just as quiet, picks up slightly at 2000, never could find an rpm that created any drone. This is my third vehicle I went with the magnaflow , I had a single on my 98Buick GS, and put two on my 97 Cobra to replace flowmasters where the drone at cruise was giving me migraines.I don't know about prior models but on the 07 it is next to impossible to find just a tip without changing the muffler to tailpipe section and getting a new longer hanger to level out the pipe.Since the price on the tip was $85 and the pipe and labor were another $60, I thought $280 for everything with a written lifetime warranty was more than fair, especially after checking several aftermarket parts places that wanted between $350 and $450 for just the parts. A single polished SS tip would have been $40 less expensive.They had some awesome looking chrome plated single and dual tips of various shapes that the shop owner guided me away from, as he said they would discolor or peel in a couple of years. I seldom make snap judgements about people that work on my cars, but this guy was one of the most straight forward honest person I've dealt with in some time.I later found out he had done work for both my son in law and a friend who had a performance shop, next door to my son in laws engine shop.I burn my own Cds and that one has a little bit of everything on it, from the Animals to Bobby Bland, Johnny Cash, Leo Sayer, John Michael Montgomery,Elvis,Air Supply and a couple others I can't recall right now.
