Exhaust tip placement? ...side, down or strait out?

[mountie]

I wonder if any difference on a sound 'tone' if I ran twin pipes from a stock style "single-in" to "dual-out" muffler to behind the wheel?

 

[NebraskaJ]

I was behind one today and noticed that. I'd have the pipe up higher and angled more downward so the angle of the slash cut matches the bumper cover. Maybe have no more than about half an inch of reveal.

I don't think this is possible... I remember there being a lot of issues with routing pipe except for a semi-stock location.

I have a cat back dual exhaust installed on my 07 Yukon XL Denali, a Gibson Extreme cat back dual exhaust system; however, I had to eliminate my spare tire, in order to complete the installation. This was the only cat back dual exhaust system, exiting behind each rear tire, that I could find.

Yes, there is a risk of being stuck SOL somewhere, if I have a flat tire, but I am going to get a tire inflator and sealer kit, and keep it in the truck.

It looks fairly easily doable to me. Maybe we're not picturing the same idea.

I grabbed a couple spare dual exit tips and tried a few quick ideas. This is what I was trying to describe, except maybe with tips that are even (these are staggered for straight out fitment on the driver's side of a G8) :

It'd be for someone that wanted minimal pipe visible but not a total turn-down under the body to cause that reverberation resonance, but what pipe was visible would be clean and simple:

I have a straight and even-tipped dual exit that I tried going straight out the back with the slash-cut tips following the bumper cover:

I like my side-swept exits, but they look a little funky from certain side angles and the exhaust pipe is visible from the back. I'm thinking of switching it up to duals straight out the back. I'll probably modify the G8 tips for this because they're a little bigger outside diameter and have rolled edges. These plain stainless ones just look like regular cut exhaust tubing.

A new member recently posted up his dual exhaust and his spare is still in place. His exits out the back. From the pics I found online, there's a pipe that crosses over just behind the fuel tank and in front of the axle, then it arches over the axle, then around the spare and out the back. Even with good heat shielding, I'd be concerned about heat getting to the Auto-level compressor and spare.

Yup.

Good to know about an alternate option for a dual exhaust system.

And, yes, I'd be concerned, as well, if my spare tire was close to the exhaust pipe, without some solid heat shielding. The auto-level system was already removed and replaced with coils, before I bought my truck.

Flowmaster

Flowmaster makes a split rear exit kit that retains the spare? I believe the one that new member has is a Gibson.

Yes, but they exit behind the tires, not like the Escalade.

Hmmm. Worth a look...

All that matters is do it how you like it.. at the end of the day it is what satisfies you most .. i added a no name dual tips out the side to a mangaflow exhaust but forgot what model number is but I love how the V8 purrs .. not too loud

 

[Jolly Roger]

Ok, so I just got all this in the mail....I hope it sounds good together. Im going to have resonator chopped off ...wish me luck.

I had a Jones performance muffler on the Burb before I changed everything up when I did the headers... different model and style though...

I had the JFP300...
http://jonesexhaust.com/Product/Jon...ow--Pack/cad21912-aae9-4680-b099-b1719f453144

Looks like this...

This was with stock manifolds, cats, and the factory resonator in place. Cold start...

Running and revving...

Just to give you a comparison.

Good luck!

Done yet?

I was thinking the same when I saw the part number. I have AP Exhaust's clone of the Magnaflow 12259, which is one step more aggressive than the popular 12589. AP's part number for their 12589 clone is XS2589. HERE: https://www.amazon.com/AP-Exhaust-Products-XS2589-Muffler/dp/B004A5OBWE. I wouldn't be surprised if this style of muffler from AP and Jones were from the same factory.

@Jolly Roger , you have a link for that black exhaust tip?

Dannnng...wish I would have seen that on Amazon before buying the Jones...
I spent a few bucks more on the Jones. What makes the AP more aggressive? The Jones, AP and Magnaflow have the exact same measurements.
I love a good deep bassy sound with no drone when it counts, I hope that is what I end up with....
