My 2cents: have it for 2yrs+ and that's the best mod i have done to any car to-date. Try going through tunnel and shift at redline, the result is ear-gasmic.

Without m-mode, it is only slightly louder than stock.

Wondering how loud this would be with Catless Downpipes.

Mainly concerned about cold start volume and highway drone.

I've got a guy near me willing to do it for $300-$400

[Dutch335]

Ok That is good to Hear Thanks for the info

I will do this mod also

do you had the possibility to compare the sound with Akrapovic or Eisenmann?

The non M mode is more or less the same as M mode before but M mode now sounds like it should. More or less the exhaust sounds like it should have from the factory. No drone too, maybe a little if you are going 90( on cruise control) and going up a good incline. Hehe

did you end up going with 2 straight pipes?

How exactly do you ziptie the exhaust valves open? Theres nonway to do that! Even if you
Did the zipties would just melt from the hot exhaust!! Whqt
Am I.missing? Explain
With pics if you have them

[chris604]

Did the mod. Cost $400CAD ($310 USD, lol) definitely a difference as you can hear. Not straight pipe loud but a big improvement. Also the bottom of the muffler is a bit dinged up but better than the weld marks i saw on other mufflers. Will post vids shortly

You can tie them to the open position using thin gauge wire from HD or Lowes. It's effective and not affected by heat cycling.

having the valves open all the time wont affect any performance whatsoever?

Thanks. But, that's my video above. I went ahead and did the exhaust mod. Much louder, but not insane.

[GTBrandon]

Going to bring this back from the dead, anyone still riding around with this mod? Any issues down the line? Any more videos than the two that we have lol, curious how the OP's setup would sound with stock DP's, valve's open vs valve's closed. Finally, anyone selling one of these already made?

I have the cut outs if you want them, they have the values and everything. You will need a muffler place or decent welder to cut the sections out and weld vband adaptors
