Decided to go with these. Going to do a dyno baseline with AFR logs before and after install. Pricier than others, but after research and weighing the pros & cons, the EVOSport shorties were my choice. Have a 3" x-pipe and tubing to replace the secondary cats and (possibly) the resonator (not sure I want to do this). Only looking for faster 1/4 mile and trap speed = more HP/TQ (NOT sound).
Great choice!! You will be very happy with them. Have had them on my CLS55 for several years and they work extremely well! Trust me you get what you pay for in this industry.

Good choice on the Evosports. I've had mine on now for over three years without a single issue (e.g., cracks, fitment, etc.). Here's a DIY post for when you're ready to install them:

BTW - Did you do an x-pipe for the secondaries? Resonator?

Shorty headers on a large displacement motor is a waste of time and money, In my many experiences, outside of AMG and Mercedes.
I would advise holding out for longtubes, and if the longtubes are Renntech or Kleeman most large market dealerships wont point a finger.
The longtube net 40HP+ for about $2500 and shorty is maybe 15hp for $1200. So the cost per horsepower is similar. I understand the sound concern tho. Just my 2 cents.
