well, i just did my first or many (hopefully) tuning on my saab. i got a 2.25" CAT back with a 4" double wall mangaflow. i was afraid that the 4" would look to ricey, but it doesn't. the double wall makes it look smaller, and it is at an angle, making it look small, again. so, it looks very nice, i think. i would put pictures, but my computer hates me... but yeah. it sounds very nice, it still has the resanator (i suck at spelling, but it is the thing that keeps the muffler quiter) on. and, from 0-50, i don't feel to much difference. but 50-100 i feel a much bigger pull, which i found well racing a F150 on...um....the track tonight. :lol: but i like it a lot. only cost me $235. next, i'm thinking about a cold-air intake with shield and air filter. what do you guys think, or recomend?
