Stillen Headers

Z eliminator · 08-12-2009, 10:16 AM

I just ordered a set from my stillen dealer in Canada. I have seen pictures of the header not lining up with the exhaust. Several people have installed the cats, headers and exhaust. I have the berk cats, stillen CBE, and the headers , Should be here in a week or too.
" Josh " how bad is the alignment ? and is there a modification that will make them fit better, or has the issue been resolved.

Thanks.

2theextreme has that setup and it needed a custom fitment job.
Stillen CBE + Berk HFC + Stillen Headers

Umm... and I was just about to order some headers while my engine was out.

2theex should be chiming in soon

You may want to visit semtex's DIY Header Install thread:

DIY: Stillen header installation

About halfway down the page the photos semtex posted are identical to the issue I had....it looked to be off by few inches. There is a solution to the issue in his thread.

The solution that Altered Atmosphere did and I agreed on, was to cut about 1 to 2 inches off my Berk HFC's. So far I've not seen or smelled any problems. I was back at Altered last Friday and they put the car on the lift and said they didn't see any leaks or any problems where they had welded things together.

did they weld the HFC to the catback or is there still flanges with bolts??

FuszNissan · 08-12-2009, 10:41 AM

Did the cut and re-weld? After reading the thread, it may be that AAM cut the thickness of the flange down an inch

It looked like this on Altered's lift:

I believe they did the first thing you mentioned.....welded the HFC to the catback.

Maybe I won't be getting stillen headers

Tony's right, the fitment of the Stillen headers caused the High Flow Cats to sit too low to bolt to the exhaust rear section. But we actually didn't weld the HFC directly to the catback. What happens is the Exhaust Manifold collector is a bit too long, and this causes everything behind it to sit lower. So it for us, it was either try to force the rear section of the exhaust and the cat to fit together, or modify the HFC itself. We didn't want to force the parts to fit, because it would put too much stress on the exhaust components, and we could almost guarantee that the exhaust would crack when heat and hanging weight was put through it.

So we had to modify the cat to line all of the components up correctly, and after we made those changes, the exhaust fit perfectly, with no leaks or any issues.

So while my engine is out I want to replace the headers, but from reading this thread stillen doesn't seem to be the choice. Are there any other headers out yet?

Tony from FI has mentioned a long tube prototype is a possibility, but nothing is final. Of course, true long tubes would eliminate your Berk HFC's.

FuszNissan · 08-14-2009, 01:18 PM

Yeah, Tony said probably in 2 months, which my engine will be done by then. Oh well.

longtubes??? INnnnnnnteresting.
