Has anyone purchased the OBX header system (with y-pipe) for their Max? I've found places offering the OBX system for $350-$400 and the Cattman system for just under $800. Were the OBX headers "cheap" immitations or are they a quality product? Which gives you the most bang for the buck?...Are the cattman gains worth paying double the "moolah"?...the Maxima community needs to know!

 

i want to know this too!

I also would love to see dyno graphs showing gains on NA maxima's of headers & y pipe combo over just a y pipe, then boosted max's as well...

 

when did obx come out with headers.....and where can you get them from?????

there, but the y pipe does not look free flowing

 

By the looks of the design of the OBX ones, we'd all be better off forking out the extra moolah for the real deal cattman headers... Just compare the design of the two and tell me which one looks more free flowing

obx:


cattman:

 

yeah I wouldn't touch the obx's if you're going to get headers. The collectors on the obx headers all meet at a 2.5" outlet, and the rear-most tube on the y-pipe meets the main pipe at a 90deg angle. Oh yeah that's free-flowing.

And there's plenty of info on cattman headers and cams with a boosted Max so just look around in the appropriate forum.
