Quietest Boosted Exhaust?

MoulaZ · 04-23-2017, 03:34 AM

With the Motordyne E370 & Test Pipes I currently have on, yes it's stupidly loud, but even louder due to the SC pushing way more volume of air through the system.

I don't have hiss, but I do have rasp now since ditching OEM Cats and going with Test Pipes.

I'm not a fan of the two Invidia mufflers on top of each other near the end, 'horizontal' if looking from the rear, how the exhaust has to make a 90deg turn to enter and like a 60deg to exit. May not be an issue in an NA application, but for an SC where you're looking for everyway to increase flow efficiency it just doesn't rub me the right way. At least Injen is more traditional with two standard 'inline' mufflers at the end.

Not sure yet about the Invidia, but the Injen exhaust is 60mm, which is like 2.36" or might as well be just 2.25", which should be a great help coming from the 3" Motordyne.
