Best exhaust vid by far...Most vids don't do the exhaust / note any justice, but you can definitely make a decision based on your vid. Well done...sounds brilliant !

Cheers

Removed sound deadening then solidified the perforated inner chamber pipes (did not swap perforated pipes with solid pipes)

Perfect in every way, although after driving 100k bone stock, the mod at first is a huge difference in sound and overall driving experience , I feel like I'm driving my 68 z with 80series Flowmaster, but enjoy the ride with the tuned rumble and have no regrets...

mine has broken in a lot... The mod was done to a brand new e92 muffler , FYI tips are longer on the e92 muffler rather the e90...it's still not as loud as if you bypass the inners completely and just go straight out the outers..

My has gotten more loose sounding as opposed to when it was new it had a more drony tuned hum, now it's more throaty and really amazing, My friend took off his eisenmann and prefers this mod better

Take a look at my video. I compared the M performance vs the OEM mod. OEM is a fraction of the cost, but sounds a bit raw. M Performance is definetly quieter with a tuned sound.

Sounds good! I was fully planning on doing the perforated mod until I heard the ESS exhaust...then I knew what had to be done...
