I am also considering LT Street headers with side deletes. Car is hitting storage in a couple weeks but some thing I may add for the Spring.
I know I said I do not need any more power but I am a sucker and the numbers are quite impressive with these headers.
Jaime- you can ship directly to Swain Tech Coatings correct??

send me this code “321 Stainless” as a PM or email. And i’ll send a one time use 10% off code valid for 6 months.
keep in mind the products are very popular. We are small and fulfill paid orders first. We are biuilding 40 sets of catted headers in the next 2-3 weeks and already 10 of that 40 are spoken for...

Jaime,
I have been living with my long tube headers/black muffler combo for a few months now, and all i can say is, WOW!!! I've owned dozens of performance cars over the years from BMW, Merc, Porsche, Audi, etc, and have installed aftermarket exhausts on most of them.... including my last 991.1 GT3, and this is the first system I have ever installed that VASTLY EXCEEDED my expectations! The sound is completely intoxicating, and the workmanship is top-notch!

Just bought a catted version for my car. On the .1 I had a set of the race headers and loved them. They were amazing on the car and never threw a CEL the whole time I had them. From my understanding on the .2 this will not be the case until they get the race headers sorted on the new chassis and why my decision swayed to catted for it.

95db at 2500rpm is no problem, valves will be closed as long as they're not unplugged...
