Weapon R long tube 4-2-1 header
Not a lot of guys here have it. From the looks, it is high quality and looks amazing. I know of one person who has it and he loves it. Its going to be hard to tell how it compares to ZZP's because all cars are different and untill someone puts all the headers on the same car and dynos on the same dyno we wont know which header is the best.
the whole problem with that is there is no space for a cat converter. It goes straight to the exhaust piping so it isn't even street legal, and most of us can't see the practicality in that.
so in that header thers no way to put a high flow cat?
(im not worry of the cat since here is preaty easy to get pass the emission test, but im worry about the sound, i hate ricey sound)
I personally think it makes the car sound awesome. At full throttle the sound i compare it to is when Crocodile Dundee takes that flat piece of wood thing on a string and swings it around to make that creepy ass noise, Thats when i had straight through 3" piping with one resonator and one straight through 3" muffler.
Ever since i put in the dual exhaust its sounded like ass, so i'm in the process of y piping it to get back that death rattle of a sound.
For performance, its a lot less peaky, you'll feel power increase throughout the rpms instead of just abou 4500 rpm. I put a catalytic converter in after the header for a while, and it didn't really drop the performance much, so it can be done. But for one, it made it have a whistle sound and two i dunno how well it actually will work being that its so far back (codes still went off too). I was using a stock cat though, so a highflow aftermarket might be better.

its a pain in the ass to install cause you have to drop the cross member to get it to fit but the quailty of the header and looks is great...seems like it put out some good grains i'd have it but cuase theres no cat and in cali cops car ******...
From what I can see looking at the pictures you would need to do some cutting before the flex pipe joint and weld in the cat, it would totally work, might need a new 02 bung also I wouldnt think its that much work really
WOW you guys are crazy... your cat goes on the DP.,,,, OH Man.... what are you guys doing to your cars? this is what a cat on an exhaust looks like.... its the big thing on the longer thing AFTER the flex pipe...
doesnt matter as long as it is after the collector...thats it, before or after the flex pipe makes no difference...thats just so you dont bust things when your engine torques back and forth...
that's the traditional way of doing it but there's nothing saying that we can't put it before. I think it would work better if you got a custom exhaust and just made the actual exhaust shorter to accomodate the cat.

i agree..you can even just have whatever you have cut...just have a shop take whatever exhaust you have, cut it to fit the dp and then reweld a flange...problem solved!
