Quietest catted downpipe + exhaust?

[James Cole]

Hello guys,

Looking to upgrade my 2.7 exhaust, what would be the quietest turbo-back setup, only looking for a very low rumble no rasp or drone...

Thanks!

Why not leave stock exhaust?

Why not leave stock exhaust?

Because I'm getting 37s on 4.46:1 M210 diffs, and I want the most power and torque to offset the gear ratio without pushing more PSI in the turbos.
I want to be able to do that and let my engine breath without having to wake up the entire fauna around me while camping.

Bumping because I'm super interested in that question too...

Not going to make a bit of a difference with stock turbos at stock power levels.
Factory exhaust flows more than enough.

But regardless, there’s only a couple different brands that make downpipes. CVF or SPD

You cannot make me believe that, every single engine with or without turbo I've owned has had a small impact on power and MPG by doing a complete exhaust... enough to recoup the cost on MPG? No... but still.

Believe whatever you’d like makes no difference to me.
