Agreed, I remember when mine was stock it had a rushing air sound even through tunnels from the exhaust and I just love the muffler delete for the price. To me it's just exposing the true tonality of the engine (well, obviously resonators are included) without any additional baffling or valves and the results are stellar. I only wish I had the elevation mod like you and lived closer to sea level lol, 6100ft at my house.

Wow over a mile high. Have you taken your car to lower elevation to see how it performs? On a side note, now that the exhaust mods are gone I'm thinking of getting one of those Android head units and doing the tune and I should be set.

I might take it out to California this next summer but never had the chance to unfortunately. But that sounds like a solid plan, I'm curious about the tune too. As for the head unit, I'm not sure which is the best model but it's been covered extensively on the forums.

I got a better video up of the muffler delete in case anyone is interested. https://www.youtube.com/watch?v=O4Nz...ature=youtu.be
