C7 Progress in The Aftermarket
- Thread starter Bru
- Start date
I was expecting less out of the headers and more out of a tune. I guess the tuning will improve as the tuners learn the new platform though. Cant wait to see the future #s of this new DI with FI and a tune.
sorry, if someone can embed this for me.

It would be nice if they came with headers and other upgrades, but wouldn't you miss the fun of building up a car yourself?
I agree, but Chevy could then advertise another 20hp stock. Would be a good selling point.
LOL, and then people ask why German cars are more expensive. Let's compare the LS3 exhaust manifolds to the M3 headers:
M3 for sure had headers, wouldn't call them long tubes, but they are headers. The R8 has headers too, not sure what they look like but when we did the exhaust you could see the header piping coming into a collector and then to the exhaust.

Exhaust has been improved over the last few decades. A stock Foxbody or f body manifolds in the 80s-90s left much room for improvement. But the new coyote has a nice tri-y header design that works well. Guys are only picking up 10-12 rwhp with larger diameter aftermarket units. I sat that is pretty good for a factory header. When they add cat delete pipes it picks up about another 10 rwhp.
The headers on the GM cars don't seem as bad either. 25hp seems like a lot. But was that the whole story? Factory cats still on the car? Or higher flow cats get installed with the headers? You know what I mean?

Yup, looks like a cost issue
One reason gains are likely minimal. Those are amazing for a factory piece.
Sound, emissions, and fuel economy. It would be hard for a big V8 like the LT1 to pass sound standard with long tubes.
Also, as pointed out below, factory manifolds (or shorty headers) have become pretty efficient. As Pratt pointed out, simply deleting the cats free up the majority of hp that long tubes are good for.
Supercharged, bitches

holt fuck it's so flat.
Direct injection actually.
My 3v has variable cam timing and it still only makes its peak torque at 4500ish
