Light + Loud + Drone-Free!  Making a cat-back muffler that sounds properly sporty yet does not drone in a Lotus is difficult to do.  We've now done it.  The new sonicFURY is an amazing sounding muffler  - watch/listen to the video clip: HERE  We used a Helmholtz chamber to get this perfect balance.  This is the first such use in a Lotus!

      This exhaust is not getting the attention it deserves. I just installed it yesterday and I am completely blown away by it. 

      When I first took it out, I was a bit disappointed. It was so tame.. so OEM, with maybe a bit of anger (think OEM sports exhaust). I kept thinking, when the 2nd cam kicks in, its gonna be way too tame and suck. But then I tried to get it to drone, AC, windows up, 6th gear doing 70 and accelerating.. Nothing.. All i heard was faint exhaust, a bit of SC whine, rattles and my passenger side window isn't sealing good. Wow.. Ok, so maybe a tame exhaust isn't that bad.

      But then I turned around and went under a bridge.. Might was well try this thing out. I felt sorry for everyone under that bridge. I had no idea it was gonna be ear bleeding, idiot with a sport bike loud. Wow again. I then proceeded onto the freeway and was going for it. Its very loud....I prefer the small and high revving motor noises vs old school V8 sound and it def delivered. Then I dropped it into 6th gear and all was silent again...I cruised all the way home, loving the zero drone and zero boom. 

      Easily the best exhaust I've ever had. To have such a loud exhaust when I want and then for it to go full silent is perfection that I've never had with an aftermarket exhaust. Its either been too quiet or too loud. I've always wanted a switch to go OEM and aftermarket, depending on my mood.
