Ford Racing or Corsa Extreme

[Bad_Rooster]

Drone is cured by forcing exhaust back towards the main stream, hence more restriction. There is other ways ....Like adding a pipe on one bank that's capped and approx. 22" long give or take, there's formulas for that, different lengths of mufflers and different length of bends etc...Ford Mustangs had different lengths of mufflers for years, only 1'" to 1.75" different from side to side. All vehicles ( NOT STOCK EXHAUST ) that I have ever heard that were even somewhat throaty have a drone at 1700 to 2200 rpm ( V8's) Some peeps like my son don't think the same way... he doesn't hear a drone, neither do half my customers, even though I hear it loud n clear. I have installed hundreds of kits and mostly custom make my own stuff here at the shop.

I was going to go the helmholz resonator route but changed the direction I was headed a bit. I have heard it works very well though.

Went with the Corsa Extreme.
Installed yesterday and couldn't be happier.
No drone and very little increase in sound level inside cab.

Nice! Stock manifolds or long tubes?

Stock manifolds.
I use the truck as a daily driver for my business and didn't want to be too loud.
Also, working on the requirement list for Raptor Expeditions Club so didn't want to blow the budget on exhaust only.
Next call this week will be over to Jeff at SVC for his tune.

Cool. You'll enjoy the SVC tune...I'll have the xtreme next week installed with my headers. I'll let you know how it sounds. If it's too loud I may go ford racing or put in the stock exhaust till I figure out next steps.
