Exhaust System for 4AGE 100 KW

Hi Guys,
I want to fit a sports exhaust system to my AE93 SX and wanted advice as what the best set up would be?
I want to get the most performance out of the engine as possible from the right set up but I'm not into loud, droning or show exhausts.
Any help would be greatly appreciated!
Cheers
Pugs

talk to a GOOD exhaust shop. IF you see a bunch of cars out the front with massif cannons, keep driving.
Talk to the guys and tell them what you want, and be prepared to pay more than $300.

id say no cat at all; its easier for the cops/rta to chck it unless they got a EGA so no matter which way if u get caught youll get a oversize butt hole  , (not to mention excessive emissions for the tree huggers)

Mine is made up of...
- Custom 4-2-1 Headers
- Small Flex pipe
- 2.25 strait pipe
- Hi Flow Cat
- small strait section
- Resinator (hot dog)
- then 2.25 inch mandrel bent piping
- lukey muffler - rusted tip
The resinator is an important part, becuase without it i beleive that 4AGE's sound shit house, the resinator drones the exhaust note alot 
Hope that helps,

Yep, focus on the muffling over pipe size. A good quality muffler, resonator, and cat convertor, will be a prerequesite for keeping good power with the exhaust system, and they will vary in quality and price. Talk to an exhaust shop you feel comfortable dealing with, and that wants to answer your questions, to work out the best priced and performance system for you.

i wanted to remove my cat. but nobody was willing to do it for me. They say $5000 fine for the shop and $2000 fine for me... or maybe the other way round...
Does high-flow cats make alot of difference? Is it worth the money??

im also looking at gettin my exhaust system done, and i have the same engine as the GTI corolla. i already have a 2inch straght through cannon muffler, and too am not a big fan of loud as exhausts that rattle the car.
where is a good place to get extractors for the 100kw engine?

Thanks for all the help guys, I really appreciate it!!
I had the car dynoed on Friday on a very accurate dyno (gives the lowest readings in Adelaide) and was expecting low to mid 50's but to my surprise, I got 64.6 kws atws from a stock motor that has done 227xxx plus kms!
So, I'm hoping after the exhaust is done, I'll get low 70's??
Am hitting the track soon to see what she does standard, so I can get a starting point before I start modifying the engine.
I've located a couple of good exhaust shops and will hopefully get an exhaust in about a month or so!
Cheers

To be honest, most lightly tickled 4AG's I've seen have made the same or better power with the factory manifold than many of the headers people fit... Don't underestimate the factory casting - however, the pipe that bolts straight on the end of it can usually be improved on quite a bit.
