Hey everyone. Well I finally got the headers installed on my 2k2 Max. With the help of 2 other people (HUGE THANKS TO CULLEN AND SCOTT) the install took about ~10 hours. The headers come with an EGR port, that is for the 2k1 and 2k. Dont know about the 4th gens. But the 2k2+ does not have the EGR. So I had to find a way to plug it up. Problem is the plug would have to be metric and big. I decided to cut the port off and weld the hole shut. I did this at a local place here in Louisville that works on lots of welding. He did a great job and saved the coating on the headers. I talked to Brian about this and said he could get me a plug but well I was impatient . But the next batch of headers that he gets shipped in said will have the plug. so dont worry about that you 2k2+ guys. Car sounds great. Sounds like a 350z now but just a little quiter. Butt dynos are ok, but true dynos is what everyone wants to see. I dynoed first with the Cattman y-pipe, then dynoed with the cattman headers. I did 3 runs each, and took the best of both runs and put them together.
Dyno run of Cattman Headers vs Cattman Y-pipe
I can find differences of about ~30hp and 30ft/lbs right around 5600 rpm, it is a lot faster after around 4k, and then it really gets going between 5k-6k. Also not this is with the stock B-pipe and muffler. Also, when I was at the Dynojet place, the guy told me I had a peak HP of 237HP and torque of 234.5. The dots on the graph shows the greatest difference between the two dynos.
Here is the data from in excel format: Click here for Spreadsheet
I talked to brian about this data and seemed very happy with it. he also told me he has one more set of headers in and more coming in mid-October.
All I got to say. Is great work Brian on an excellent quality products and excellent service. This is why I have tons of Cattman parts on my car.
