It makes the car look so much newer/nicer and I was surprised on how much better the headlights lit up the road after as well!
These Kleemann headers also showed up on my doorstep, just waiting on the new gaskets and nuts to show up now!

Would you mid please taking a picture of the collector and 1-2 ports? I would really appreciate it. I am thinking of getting some kleemanns as the only local shop I would trust to do long tubes wants $3,000. Probably worth it for the quality but still too much to justify.

That is quite expensive, I just got these from Kleemann's official ebay page for $745 shipped! All I needed was the new manifold nuts and gaskets for $45 and a new Eurocharged map to tune for the headers and O2 sensors. Local shop will install for $400!

I bought one and it was bad. The car wouldn't even move, it just wanted to die.
Ended up returning it. The process took a month....never again will I deal with them

I would get a code reader and check for any stored codes. See if there is anything stored relating to your MAF or otherwise! Some people don't realize that your car will store certain faults and not throw a CEL or dash light, especially if it is intermittent like your situation!

I think I will get some of these when the time comes. The main hp gains are to get rid of the extremely restrictive stock flange at the end of the stock headers. This will do that nicely. The guy at the shop showed me some beautiful 4-1 merge collectors with perfect taper point etc but the extra 3hp really isn't worth another $2k. I am sure you will let us know how you find them.

Now I have to decide if I want to spend the $122 for an official signature badge, or just get something cheap from ebay!


Kinda random question: On your Needswings DCAI, did you have trouble with that large rubber elbow constantly slipping off of the throttle body? Mine is a real pain to get secure with that hose clamp routed down the back of the engine.
It kept slipping off when the other intake piping and filter cans are connected. I finally got it to fit alright, but just had to take it all apart to get the car smogged- now it's back on with it...
