Cool. Thanks. He mentioned unichip... I wonder how it would have done with stock ecu. That's some pretty nice gain.

Finally installed my headers!!!!!!
My 430 is now supercharged with headers!!! But no mashing it until I get tuned

Let me just say. The installations was a b***h. I haaaaated it. Dam heat shields. Lets just say I'm going to have nightmares if I see them again. So I'm gonna take them out somewhere and shoot the crap out of them with my xd40

So in the last few weeks i have installed a supercharger with injectors into my 430 as well as the headers.

The headers were so much more difficult to do than the supercharger. I would rather install 3 superchargers than one set of headers!!!

just an update. Car is on a street tune. Headers feel awesome and compliment the exhaust setup quite nicely!!!!!!

FYI, for those interested, and those who helped in put this exhaust together..

So... a year and a half later, how are the headers holding up for everyone that installed??? Is it worth the price/install effort?

Hate to bring this back from the dead. Figured it's the right place.

How's everybody's headers holding up?
Anyone got videos of how they sound like?

My 3rd gen headers have cracked which I have gotten repaired. Other than that they are still performing and sound good. I'll see what I can do for a sound clip. It's hard to tell because I have the Carson Tune full exhaust plus the headers but I still get compliments on how it sounds all the time.

I have had the PPE headers on GS400 for about 15 months now. HIghly recommend them and have had no problems. Did it with SRT intake+piggyback and have had 0 CEL from them. I did have a p0420 a few months after install, which was a bad o2 sensor and has not come back since. I do not believe that problem was related to these mods.

The driver side header by the steering shaft kind of rubbed+squaked for the first couple days when turning the wheel, I guess it ground itself a little clearance and has been silent ever since. That driver side install is not something I wanted to revisit lol
