cat-back might not be the best way to go first. you'll get more room for expansion off the exhaust header if you go with an upgrade from the header to the cat first. in fact, look for an exhaust system from a 2.1l engine, from manifold on back. should be able to find a junker somewhere. it will increase size from 1 7/8" to 2 1/2", and allow you to use the turbo muffler and cat. as far as the intake, remove the cone off the air box, remove the box from its mounts, pop off the top and turn the bottom so the intake lines up under the driver's side headlight. then, take off the amm and loosen the clips for the intake bellows. spin the bellows so that they start at the throttle manifold and make one 45 degree bend towards the driver's headlight; cut off the rest. put amm back in bellows and re-attach to filter housing. you'll have to re-mount the housing, did mine with zip-ties for temp fix, and works fine. haven't done it yet, but you could then take plastic trash can and cut/modify to create a ram into the housing. just recently had head work done for turbo engine rebuild by very reputable shop here in seattle. he works on everything from trucks to cars, to race and rally engines as well. said the saab heads are seriously under-ported, but leave an enormous potential for upgrading. we'll see how well it turns out once i get the engine in. i ended up building a turbo engine in the garage and should swap it into my 90 900s. i started down the road of performance upgrades with the n/a, and with the exception of intake and exhaust work, i hit a wall. everything else was going to require a lot more money that i figured would be better spent starting with a turbo engine. note: spoke with swedish dynamics about cams (as i had heard differing opinions about their cams for n/a cars) and found out they wouldn't stand behind their product enough to allow for an unsatisfied return. basically, you buy something from them and don't feel as though it meets their claims, you are stuck with it. just my two cents. good luck with your mods.
