I did forget to get the stud above the AC compressor I did have to double nut the stud and remove it that way

Started about 10 this morning. 1 o’clock and the car is in the air and passenger side factory manifold is off. Gonna keep rocking.
I wanted to add that on our cars taking the under pans off makes this job much easier to complete!

Also for you viewing pleasure, since I had all the underpinnings off it gave me a good chance to look at the coolers, I have attached some of those pics also.

So did the adapter pipes from the headers to your Switch fire come with your headers? So did you have to modify Anything for the install. Thanks

Yes this system was to fit a factory cat back system and the SwitchFire is factory in and out

Looking forward to sound clips. I’m going to try and quiet mine down.

Yeah, you will want a resonator in the mid pipe section even with catted headers. Catless really increases the volume even further.

Are there any good resonated H-Pipe or X-Pipe options out there? I know how brutal the bark\rasp can be with headers and the resonator really helps along with the cats if you want to keep the stock exhaust on.

Otherwise, I may just keep the full stock exhaust and that resonator in there too.

I know magnaflow and Borla have one.
Not sure who but I know one uses v-clamps.
I will prolly get some small resonators from Vibrant to put in post mid pipe. Location of the resonators plays a large part of what they do. Perhaps even where the factory bottle neck is. Cut that off and put a 3” resonator in there. Not sure.

The Krona catback I had on my 17 GT had a small x-like resonator in the mid pipe section and it made it sound incredible. I definitely think it needs to be closer to the front\middle. I did Vibrant resonators in the rear on a Corsa Sport setup and it was alright but the Krona setup was way better with headers. Even when I went with catless lead pipes, the Krona catback sounded really good still and not really raspy.
