Go equal length on headers if you can possibly afford to. Because part throttle.

EL are equal headers and UL are unequal length headers. Both types are available for the ISF and the RCF from PPE. In addition EL hearers are available in a short version on one with long tubes, again from PPE.

Novel headers are also equal length. 2 versions, one catted (like oem) & one without cats, both equal length. JDM would never tolerate part throttle ul sound.

What's the difference in performance/sound between the EL long and shirt tube headers?

This may be an odd question but, what's the highest pitch exhaust setup for our cars? Or how would one achieve a higher pitched V8? Not talking F1 high but just a higher note than stock and the typical boat sound.

Are the Novel Headers made out of Titanium or SS?

Borla with a muffler delete keeping OEM tips. Not much more drone than regular Borla surprisingly, though did take a few hundred miles to calm down a tad. love it!
