Trial and error sucks but usually gets you the best results.

That’s why we wait 4 weeks until the Long tubes come out

FYI- afes LTs are out for sale.

Kooks said they are 60-90 days from releasing LTs. I'm still debating because $1,500 for 20hp is a lot.

Agree

Bump...any personal info on LTs or shorties installed?

 

[cj7]

Is it my skeptical eyes, or does the baseline in the LT dyno graph not look right...

Funny how their baselines for the ST, exh and LT are all (meaningfully) different.

I want to believe, but ... maybe someone with real-world experience can convince me, ‘cause I wanna believe!

^^^^ I don’t disagree. I’ve been talking about that for months.
I’ve done a lot of reading and talking to multi aftermarket companies. One thing that I’ve found seems to be across the board. The 5th gens respond a lot more positive to manifold upgrade compared to 4th gens on stock tune. regardless of short or long.

Yes, I just sent a set of those back to Summit. They were awful. After removing them I found the drivers side flange warped. Probably why I couldn't stop the exhaust leak...
