You might need a little bit of hose to connect it. Then you can just tie up the others or just leave them where they are. The part number for the 6 inch cone is K&N part # RE-0930. I don't know how much the full exhaust 3" dp to 2.5 duals is pretty steep!! [Image: confused.gif] If it was me I would do full 3" exhaust. It would be cheaper. Some say it is ugly and they would think rice blah, blah. I say let them think it. They will probably get a good veiw of your tailpipe at the light anyway. [Image: tongue.gif] Anyway enough of my ranting. Hope this helps you. Maybe someone else on this list can give you a price tag on the exhaust.

Just went through engine swap with a wrecked 1987 Turbocoupe. Going to become a street legal racecar to tinker with. Have a T3 waiting to go in when I get everything ironed out.

The Gillis valve will come with all the parts you need to install it including hose. This would be a good time to inspect all your vacuum hoses and replace any that need it. If so you will have to get hose to replace the bad ones. You will get instructions with the kit. If you want to read them early see the article in the Technical Articles section. There is also a diagram there.
