No egt or intercooler yet, hard to do work when you dont have a garage and its -5 outside.  I usually keep it under 15lbs with small spurts to 17 or 18.  Intercooler and egt gauge coming when it warms up!

GB-  I would definitely buy one if the pocket allowed, being a broke ass student thought doesnt seem like it will for a few more years

GB doesnt understand the whole "using your money for more important things" kinda life style. appearently he has more money than he knows what to do with. and everything he does is perfect, just ask him. hahaha.

i hear ya tho, gotta save the money to keep the car running, not to put TT exhaust on it.

guys, regardless of valve overlap and a need (or lack of need) for back pressure, you can have too big an exhaust.

It is said that if you go too big, the exhaust gasses expand too quickly, cool off, and slow down, thereby creating the very same back pressure you're trying to eliminate.

What's the best exhaust I can put on my 92 1.6l n/a ?

I have an all stock system and want her to breath better!

"Best" is highly subjective. On my 1.9NA I use a 8v GTI 4:2:1 stock header. I had to add a spacer though because the 1.9 is a bit taller then a 1.6. It will bolt on a 1.6. What you can also do is hollow out the bottom of the "toilet bowl" and increase it's diameter up to 2" or 2.25". I wouldn't go bigger then that on a NA. If you do some searching I think you will find what you need.
