So how long would it takes for us to get a HP gain # and tor on that header ?? =)

UPS will be dropping off my headers today and I will be installing on Friday. I will also be doing a before and after dyno Friday, so stay tuned.

I would wait about a week, before doing the after dyno, as the car needs to adjust to the headers.

I will also do a dyno a week later or 500 miles which ever comes first for a comparison.

If the dyno is a DynoJet, please make sure you take a 3.5" floppy with you so you can get soft copies of the data files. That way we can do all sorts of comparisons using the free DynoJet Runviewer software.

sorry no DynoJet. It's a DynaPack 3000 Chassis Dyno.

lookin forward to the before and after dyno. Also quiet curious to see what the diff between the freshly install and 500miles later power figures.

Thanks for posting the pics! Would you please take a picture looking into the collectors?

BTW, the primaries don't look equal length. That's a bit disappointing.

Toptier

I will take some pics when I get home from work.

For those experienced with headers, how do those merge collectors compare vs. other high quality headers?

My headers looked the same. Make sure you buy some new gaskets before you install the headers.
You will want to get new compression gaskets, to connect the headers to the rest of your exhaust. You should also get new header gaskets. This will help minamize any leaks in the system. Trust me, get new gaskets...

The 1st 2 are very close, the last one is a little bit off. There is just no room in there to make them all the same.
