New Exhaust Setup
Guys,
Had my exhaust redone and wanted to share some pictures. Basically he removed the 3rd cat and both resonators, ran 2.5" piping, custom made an X Pipe and then the duals run back to L-Tuned mufflers. All piping was mandrel bent.
Difference? Well, it is a lot louder. It is an aggressive loudness. Certainly gets peoples attention!! I will get a video of it soon so you can hear it. Here it is
I am not sure whether there was any HP difference. As soon as I get the headers in and get them installed I will be bringing the car to the dyno to see what she has
And here is a picture of what was removed. I was impressed to see that our cars have mandrel bent piping.

looks good, I was thinking of doing the same thing. Still comtemplating the removal of the last 2 resonators. Looking foward to hearing your clip....Probably makes a mustang blush

Need to find someone to do the video for me. (That way I get to show off my new car

Where are you getting the headers from? The craftsman that JBrady is working with, or another place?

I will not rest until I am getting 300hp to the wheels

On one hand I am pleased to see someone make the effort to improve their system.
On the other I think you will see a loss if low to mid RPM torque/response. Why did you choose 2.5 pipes? A single 2.5" supports well over 300hp. Duals is WAY more capacity than needed.
Sorry to sound negative but I prefer others not go with these size pipes. In fact I am planning dual 2.25" feeding a single 2.5" pipe center pipe on a Y to Y ( >-< ) style system. The stock center pipe is 60mm so increasing that to 2.5" gains around 13% in flow area. This is enough for most applications. With exhaust you want the SMALLEST pipes that will support you peak power in order to maximize off peak power.
BTW, you did not have a 3rd cat. That is a resonator.
Anyway, nice to see the effort.

The reason I went with 2.5" pipes is because that is all he had for mandrel bending. Either 2.25" crush or 2.5 mandrel - so I went with the 2.5" mandrel.
After speaking in depth to my exhaust guy, he said that it would be more advantageous to go with an X pipe going back to duals than a Y pipe going to single and then back to Y.
Regardless, I may have lost low end, but I sure didn't notice it.
I am hoping the headers will take care of these problems.
3rd cat/resonator - lets call it restriction!!!
What's the latest on the headers? Did you receive them yet?
