Back pressure is bad for any motor, but you need to keep up your exhuast velocity.
Here I go again with teh combo
SDJ header
Borla XR-1
N1 knock off.

ROTARD FOR LIFE!!!
awww, dont be so hard on him. For some of us, this was the thing that got us into cars...
now if you get the idea to put a V8 in your car, then sell it
(jk, dont blow a head gasket lol)
Welcome to the forum, and I have heard lots of good things about the RB Headers and Catback Exausts... from some claiming a 40hp gain. Even if it werent true, maybe it was enough change to make them think that. and as Dreyko said, try to get it off the forum. you might find a better deal from a REPUTIABLE member

Im not positive here, im sure someone else can help if im wrong, but i think you need the air pump to open the 5th, 6th ports. And I dont think changing the exhaust will make your ports not open. I know the racingbeat exhaust doesnt effect the aux ports, not so sure about others though.

Your 5th and 6th ports are intake ports on your motor, they open up at higher RPM to allow more air into the engine for a bit more power.
Now on an S5, your 5th and 6th ports open up with the air pump. So you removing your air pump has eliminated your 5th and 6th intake ports. Either put your airpump back on or you can wire open your 5th and 6th ports.
If you're thinking of selling your car because you don't know what 5th and 6th ports are and don't know how to read the FAQ at the top of the page... good luck.

as far as header,straight pipe and maybe muffler maybe not. its going to be LOUD. I mean like cop bait almost. right now I have a header into a test pipe then a motoria exhaust. it's semi ok at lowrpms low loads. rev it up past 3000rpms at WOT I need to wipe the blood off my ears. if you like loud that might be fine. just expect to be easy ticket bait and also it does get tiring after a while as well.
so yes yo uat least want a muffler in the back rather then no muffler like it sounds like you might have been debating on. then you want to put another muffler in where teh cat used to go rather then a straight pipe. it will help a little at least.
as far as headers you have the racing beat though don't know if they are still around but a company named mindtrain used to sell headers as well. from what I understand they had good stuff and might even be better then racing beat.

i just wanna fix my car
i think my car is just a regular gtu not a gtus,
if that makes any diffrence do i still need to put my air pump back on? i really dont want to, cant i wire them open? or would it run better with the air pump than wire'n the ports open?
so if i run a header no cats and a good muffler it will sound loud up at the high rpm's and acceptable for crusing at low ones? and also will it sound raspy?
"If you're thinking of selling your car because you don't know what 5th and 6th ports are and don't know how to read the FAQ at the top of the page... good luck."
That has nothing to do with ports, i was just assd out that day and it happend to be the day i got some gay thread from some 16yr old TOOL-BAG and i let it get me down....sorry bad day.....i just wanna fix my car ....and i cant get any threads i find usefull on the dang search ,im probally just doin somethin wrong
PS..I dont get down with neons and stickers

If you arent sure if your car is a GTUs or a GTU then heres a good checklist to figure it out.
Things to look for:
Manual window cranks(GTUs did not come with power windows)
No adjustable steering column
205/55/R16 sticker in door jam
No sunroof
Aluminum hood
No rear wiper
Cloth interior
Paint: Black with black interior, red with black interior, white with blue interior.
Radio has no cd/cassette
No map pockets on door
If you get to drive the car, you should be at 4,000rpm at 80mph in 5th gear.(4.33dif)

Yah, i copied and pasted that from an older thread i posted it in. The diff is indeed 4.30.
All the things you mentioned could have been changed. Mine came with different seats and a lot of stuff taken out. Also that could be a dealer installed sunroof. Best way to tell is the sticker.
The aluminum hood will be really light and you can lift with one hand without any problems. The steel hood is quite heavier. You'll know the difference.
