i used the vmk10-250 muffler. if i were to do it over again, i think i would go with a smaller can and probably round rather than oval. at the time i wanted the biggest can they had to make sure it was quiet. Built, and shipped i came in at $1038.
Total catback weight is 30lbs right on the button. Sound levels taken from a free android app so only for the sake of comparison:
- stock muffler cold start - 87db
- stock muffler warm idle - 75db
- varex cold start closed - 84db
- varex cold start open - 90db
- varex warm idle closed - 70db
- varex warm idle open - 80db
You can hear in the video it sounds a little funky with the butterfly closed as it idles down. It is only at about 1200 rpm and seems to be a resonance spot, other that specific rpm it sounds like the stock catback in the cabin. Either way i don't plan on keeping it closed much, once you open it up, it sounds very nice to my ears anyway.
Inside the car, it sounds like the stock catback when the valve is closed, and just a bit louder than the nameless 3" axle back was when it is open. this is exactly what i have been looking for and i want to give a
huge thanks to the guys at @FT-86 SpeedFactory for knocking this out for me.
Still need to modify the front pipe and catback connection point to get rid of the 2.25" step down at the doughnut gasket. Will try to get that done in the next week or so.
Better video's to come...
