got some used Altima 3.5 headers. Had them on my 98 Maxima but changed to OBX V2.

flanges on headers has been modified when I had a custom y-pipe made for them.

Altima 3.5 Headers $100 + shipping in USA|48

noticeable power?

Yeah they're noticeable like any other true header setup

Custom y pipe huh.... Hmmm

Any pics of the y pipe you used with these? Not looking to buy, just curious.

I have a few.

Design was the last thing considered, it was 6pm and the shop was technically closed but they did what they could since I was running open headers from the initial header install.

It was a last minute job at a mom and pop shop. Header install took all day for mechanic so the y is not really what I wanted but it worked for the time being. I was gonna get it redone but got obx v2's now
