I don't know what size the stock 95 exhaust is, but my stock 97 intermediate pipe is 2.75". I used the 3" and it fit perfectly. By the way, anyone need a 3" electric cut-out? When I bought mine from Quick time performance, they sent me two. So I have an extra brand new electric cutout and cable, all you need is the switch, and a 35.00 cutout pipe. The kit retails for 200.00 shipped......

I will buy it for $150 + shipping since I don't really need an electronic one. E-mail me.

Sorry, the extra one I had just sold on ebay. You could use a 3" cutout on a 3" i-pipe if you butt weld it instead of overlapping them. It would be a little harder to get good solid welds all the way around though......I think they make 3 1/4", that would be your best bet.....

Ok, I want to get the Electric cutout but I just wanted to make sure I understood what was Jegs, Summit etc..was showing on their websites as far as the elec cutout.

So, is the electric unit sold by itself? Or does it come with the Flange?

If the flange doesnt come with...... 3" flange to 3" electric cutout right..? I would assume so...Since Ive never seen this part....I cant really picture in my head how the unit fits on the flange as far as the open/close fins opening up. The fins open up the same as our intake right? The pictures Ive seen are too small to determine.

If any of you have pics..I would love to see....Thanks
