The EL midpipe is the only modification I have to the car. It is a stock 2017 F80 with OEM downpipes, OEM ZCP back exhaust and no modifications to the tune.

Nice. I honestly love the way it sounds in efficient-it's buttery smooth. The stock catted hi-flow downpipes make all the difference.

I had the car on my lift last night to swap the exhaust after picking up the new Akra. Where the gaps in the clamps were, there's carbon/soot blown down the pipes in both directions. Def wasn't sealing completely, and even after a year, the "buildup of carbon" never sealed the gap despite their claim that it would. Pretty disappointing for an almost $1,000 midpipe to have never been right from the start!

Reading this thread makes me tempted to try out the equal lengths, currently have the VRSF single mid!

You should, it's a game changer. I enjoyed it.

man im getting so many compliments about the exhaust lately. would always get thumbs up and stuff but now way more people commenting on how the exhaust sounds ridiculous. efficient mode (i cant tune out the burbles) + valves open = music to my ears. sounds like a GTR down low but screams almost like a GT3 up top to be honest.

Heck yeah - itís hard to explain but that top end scream really adds another dimension to the car and gives you another way to enjoy the car on the street/public roads

My main issue is that in order to get the right sounds I am asking for the cuffs

I found myself running long 2nd gears just to get that note more than often. It's addicting.
