well either which way, Opinions aside, Dyno numbers don't lie. After talking to the Thorley guys for a bit, they seem like they've done their math on constructing this header to flow smoother then OEM and produce more lowend torque/hp (Idle-4500).
And, the response I got in the E-mail was also re-assuring to anyone who is thinking of buying the model I listed.
"Hey Brandon,
That is actually a catalog error made two years ago. We have recently reconfirmed this to fit the 5 speed manual trans.
That model will work just great for you!
Thanks!
