Alright I decided to get the Pacesetter header for my 99 G20. I think I'll be the first P11 owner to get one. but when I called Nopi they were out of stock till mid September. Does any body know where to get one CHEAP. (Other than JC whitney, I will never buy anything from them)

I was also thinking of changing out my stock resonator with a glass pack. If I get the biggest Glass pack that will fit in it's place will my car be quieter or louder. (perforated) Also what is the diameter of the stock exhaust pipe and how long is the factory resonator. right now I have just an axle back set up. I am loking to keep my car the same if not quieter while upping the performace.

If you get the PS header, or any header for that matter, change out the stock resonator.

I have the axle-back Nismo Borla muffler on my car with the stock piping and resonator. After installing the PS, the exhaust note changed for the worst. Friends say its not too bad, but if you are picky about the way your car sounds like I am, invest in a nice glasspack.

Amen... other wise your'll sound like a fart in a can.. well not that bad.. but I would recommend the res...

the sticky kind too ;)

But for reals get a res... it will keep em bees away!

Dude, if i were you i would call back nopi and ask to speak to a guy named German. Supposedly another guy that works there gave someone on the board the info that you got, yet when they said people on the forum just ordered some from German and received them, he doublechecked and found out that pacesetter did indeed have stock. And this is only last week. And of course, definately hook up a nice thrush glasspack, as least 18". The header will make a nasty buzzing noise, trust me.

what is the biggest glasspack I can fit in that place of the factory resonator and what is the pipe size. I'll try German tommorro and see what happens. (no german jokes)
