Re: Mark's Evo IX MR Winter Projects

The car has been still rocking along. It's been a reliable car, for the exception that I stripped teeth off of second gear about a year ago and I had to open up the aem ems to replace a low side driver for mivec control. Other than that not too bad for a 770whp car! The exaust is annoying loud, it's got 3.5" aluminum exhaust with vibrant mufflers. My little project was to quiet down the beast!

I decided to try to make a larger muffler, since there were no alternatives in aluminum.

I just finished it up and it did exactly what I wanted, it's got a deep tone with no more weird resonance, and it's very quiet. Should be a good summer!
