Old school performance upgrades advice

Hi. I’ve decided to do some old school mods to me 1600 driver (1991). I wanting to go the sleeper route. From some research it looks like the gti 8v cam drops in. I also have a Weber already. My questions relate to the exhaust side. It looks like you can fit the gti 8v manifold. I’ve found one that have a 6 stud fitting, which looks like it will flow much better than the stock c clamp type. What gti years had the 6 stud type? I’ll need to get the correct down pipe to suit. I think I’m right in saying the rest of the exhaust can be the GL 1.8l exhaust, which will allow me to keep the stock tail pipe. The car also has the late calipers vw2, so I think I can also fit the 8v gti vented discs and pads too, but it would helpful if someone could confirm. Thanks.

Cam will drop in, GTi manifold will fit.
I went straight to a 4 into 1 stainless manifold on mine, but would recommend adding a heat shield for the steering column boot if you do that.
The exhaust I put on was GTi manifold back, with the gl back box to give single pipe, so no need to cut the rear valance.

You can move to a GTi dizzy to make it run better as well

Yes you can add vented discs just make sure you buy the thinner pads

Thanks. Really hard to find a Mk2 GTi downpipe these days, but I've read online I could fit the Mk3 Gti/Corrado downpipe, and use a cat delete pipe to connect it to the stock exhaust.  I now have all the exhaust sections, except the downpipe, so I need to track one down.
