Which muffler for my 2015 suburban?

[2k10silverTahoeLT]

Wanting to replace the muffler and will also remove the flapper valve, with that being said I have a couple mufflers to consider

1 and 2 chamber generic Flowmasters

18" long round case MagnaFlow

SLP Pro-Flo oval body muffler

****** Aero chamber

Which would you guys prefer to use?

Magnaflow

I would put a 18" magnaflow and leave valve on for a bit less tone during cruising but that just me.

The body is actually 24"

If I wasn’t partial to a 3.5” exhaust system for my 6.2L Yukon XL Denali I would be getting an SLP exhaust system without hesitation.

My previous DD was a Trailblazer SS with Kooks 1-7/8” long tube headers and an SLP cat/back exhaust. Great tone at start up, zero drone around town, zero drone on the highway, and great sound at WOT.

Mangaflow is typically too quiet, barely even noticeable compared to stock.
Corsa’s sound good but are usually on the louder side.
SLP is a nice in between sound level with or without headers. And isn’t too raspy, clean deep tone and good sound level.

If SLP offered a 3-1/2” catback system I’d be going that route. But since they don’t I haven’t made a choice on an exhaust system yet.

I've had the magnaflow for the last year, it's fairly loud. I like it but my wife HATES it. I'm actually looking to either swap back to stop or go with something tamer since she is now the primary driver of the yukon.

Maybe you could swap with someone? A couple of cuts and a couple of butt-joint type clamps, good to go...

I was actually thinking that, im in Metro Detroit and would be down for that.

And I'd love to help but I'm over here on the left coast. Shipping would kill me.
