Exhaust for 2015 6.2L.....

[bosro]

Yes I've read a billion threads everywhere....

I tow a lot so drone is a very important factor for me.

Problem is this truck is too damn quiet....my EB had more rumble!!

So which system will give me some sound but no drone??

Corsa is on the louder side, but is drone free. If I had the cash, that is the route I'd go.

X2 on Corsa. Put one on my 15 HD and love it. Real sweet snarl, and cruising its damn near stock.

"drone" is very much up to opinion - any aftermarket exhaust is going to create more noise than stock (for the most part) and whether you interpret that as "drone" or "sweet thunder!" is entirely up to personal opinion.

 

I have had 4 vehicles equipped w/ AFM and having exhaust - '07 silvy 5.3 w/ magnaflow, 08 G8 GT w/ LT headers, magnaflow, '14 5.3 Sierra w/ Flowmaster Force II 50 series catback, and I am putting a Gibson exhaust on my new '15 6.2 Sierra

 

IMO - many would say the magnaflow droned w/ AFM active - I removed it on the G8 (ended up stalling/camming it too so drone went out the window and in came LOUD)

 

The Flowmaster had NO DRONE - NONE, but is very tame.

Supposedly the "only" catback that guarantees no drone would be the GM supplied Borla - officially.

 

If I could live/get used to the "drone" that was present on the '07 silverado w/ magnaflow personally I wouldn't worry about any exhaust. I like hearing the engine do its thing. If the cabin noise/drone/AFM cycling bothers you after you get your exhaust on you can always turn it off.

Absolutely no drone on my 2015 6.2 with the 12909 Magnaflow. Removed the flapper but left the resonator.

Off Topic: I had an 09 G8 GT, DOD Delete Cam Swap as well . Were you on G8Board and GRRRR8 as well? I went through just about every exhaust on that car trying to get the perfect sound!

G8board I think

 

JBA LT headers (no cats) into magnaflow X pipe into 3" straight pipes custom bent into magnaflow axleback, had a vararam intake and a "baby" cam/stall package - I think stall was yank 2800, custom grind cam from local MA tuner.

 

Thing MOVED - and was loud as hell, I DD it for 130k+ miles taking it all over the place including numerous ski trips to a friends cabin up in VT had a 70 degree incline driveway always covered in snow. I ran studded blizzaks - you wouldn't believe some of the looks I'd get controlled drifting that beast during the winter, the way it sounded, looked, and pulled people couldn't wrap their heads around how good it was in the snow.

 

50/50 weight dist, stability control, mechanical limited slip, and SNOW TIRES + ability to start from a dead stop in 3rd gear = amazing

GM Borla. No drone, even when towing.

Cool, good stuff. I DD'd mine for the first 2 years, was a beast in the snow. Then after the Cam Swap and all, it was only driven in the summer for the next 3yrs, then sold it. Still can't believe those cars hold value that well, sure was an amazing car.

[bosro]

I ordered a GM Borla today....not cheap that's for sure

They should hold their value that well - was a perfect combo of power/size comfort looks etc. It handled like a 3 series, had the interior size of nearly a 7 series, RWD, highly mod-able V8, perfect 50/50 weight dist. etc.

 

I still find it astonishing and a bit sad to be honest that the GM marketing people didn't know how good that car was or how to sell it. Now the Chevy SS is about to die and TBH the ONLY reason I didn't get into one of those when I was shopping for a replacement for the G8 was a) originally they didn't come w/ a manual now they do damnit!!! and b) the staggered wheels....TOUGH to deal w/ on a heavy RWD performance sedan, you can't rotate and tire changes get $$$$

 

Why on earth they labeled a FWD rental car an "Impala" when they already had an Impala sitting in their lots w/ the Chevy SS.

 

I don't care what anyone says, the Chevy SS is the modern day equivalent of the Chevy Impala, not that POS 4 banger FWD crap they sell.

 

I mean its almost scary that GM is this inept....does Dodge have trouble selling the Charger? Hyundai did so good w/ their RWD platform Genesis now they make an Equus - oh well.

[Rawyzf]

Yup, it is what it is. GM should have known the G8 was a winner. G8 GXP is on my list, of couse M6 only. That is one of the main reasons for selling the G8, wanted a toy that was manual.

[robvas]

I had a G8 too, but only a GT. Custom H pipe, removed the resonator and Dynomax Super Turbos. Sounded great, no drone.

Some good taste on this forum ;).

 

I went:

Borla Catback

Kooks Mid Length Headers Catted - Borla Catback

Kooks LTs Catted X, Stock Axel backs

Kooks LTs Catted X, GXP Axel backs

Kooks LTs Catted X, SLP Power Flo

Kooks LTs Catted X, Kooks ABs

Kooks LTs Catted X, Magnaflow ABs

Kooks LTs Catless X, Magnaflow ABs

Kooks LTs Catless X, Kooks ABs

 

I'm probably missing one or two, that is all I can remember for now. I am pretty sure I went with about a dozen wheel/tire combos as well.
