What about the 44 series

It's possible if you can figure out placement. The inlet on the factory muffler is angled up, so if you cut it off right where it enters the muffler, it's possible you could tuck in up there, but I'm not sure about the length which might be too long to get two 90° bends coming out. Lots of possibilities if you can figure out routing. The biggest challenge is using the factory dual exhaust tips. If we were talking about a single inlet, single outlet muffler this would be alot easier, lol.What about the 44 series
Flowmaster 9424472 Flowmaster Super 44 Series Chambered Muffler
Flowmaster's Super 44 muffler uses the same Delta Flow® technology found in our larger Super 40 mufflers. The Super 44 delivers a powerful rich tone and is the most aggressive, deepest sounding, highest performing four-inch case street muffler we've ever built! Constructed of 16 gauge aluminized...
I know what he's saying and he's not really wrong, just looking at in a different way. There is a post a page back where I tried to explain how we were saying different things, but were both right. The main difference relates to how and engine is dynoed vs how a vehicle is dynoed. An engine by itself cannot make more power without tuning, but an engine in a vehicle with factory intake and exhaust can make more power without tuning simply because it's already been restricted.
That's why I always specify WHP when talking about gains, since it makes it obvious that I am talking about gains at the wheels and not at the crank.
I don't have time to look under my LT, but here is what a quick search shows.
Happy we're on the same page with knowledge base. Some here have already hopped on the oh shit it can increase my power to 165hp train.... That thinking was always really rough on the camaro forums still is. People think a Downpipe and cat-back is gonna give them more HP then what the factory says. They get very angry when they go to a dyno and learn it's generally not even close with most mid to low tiered performance vehicles. I've caught dyno operators fudging numbers at dyno days before... never a cool thing to do I was a 1/4 mile track junkie for a good 4 yrs until I got the TB and I can't count how many people would lose their shit and go ballistic when they kept losing to what they thought were lower powered cars. I've seen it with some high powered vehicles as well.
Thinking you missed my intention adding an intake and exhaust won't get you more HP or TQ at the crank then the manufacturer states. It will gain you more whp/wtq absolutely but if you've dyno'd many cars you know the bulk think differently until they actually do a baseline. I've seen anomalies sure but those were on Performance vehicles which the TB with it's 9 speed or CVT is not.
You're right and I'm not trying to target you specifically. I just know from my personal experience owning and modding turbo cars that there is definitely gains to be had without a tune when dealing with intake/exhaust. The problem is that without good testing methodology, we can only guess as to what will produce gains. There's a good chance that a less restrictive exhaust will produce good gains, but we don't have any proof yet.
I also did bracket racing at Sonoma Raceway aka Sears Point for many years. Running the 1/4 mile gives you a good baseline to start with. When you add anything that "should" produce more power it will be evident on the time slip using 60ft, 1/8 mile, 1/4 mile and trap speed. You can actually use those numbers to calculate increases or losses more accurately than a dyno. I really miss running 11's in my old Z06, good times.
Yup, that's how I did back to back testing for quick mods like air intake or filter changes. If it's not back to back or at least same day the results aren't comparable same with Dyno results.
Drop in K&N, then remove rear section of exhaust with muffler where the 2 bolt slip fit flange is and run a pass or 2. If you have another car or friend with you it would be possible to do a comparison with/without exhaust. It's actually quieter with the whole section removed than the setup I'm trying. For safety I suggest using a small piece of wire to support the exhaust pipe like a temp hanger. There is a flex joint in between the cat and the front muffler/resonator so the exhaust flexes pretty easy. I think anyone who tries it will be surprised how much more low end power there is. 🤯
