This thread is kind of for the benefit of the newer members. We can sit here and say what sucks and what doesn't, but posting some of the stupid mods that you've done might steer the newbies away from doing them themselves.
I'll be the first to post my silly mistakes.
1. Ebay "clear" side markers, man those thing's are retarded. I just put the stock amber ones back on.
2. HKS SSQV, this is obvious. I loved the bov sound, but it gets annoying after about 3 days. Plus the afterfire pops get pretty freakin' loud.
These are the only ones I can think of for now, I'm sure that some might think the K&N short ram that I put on is dumb, but I have EM, so,
.
Don't be proud, I know everyone's done something to their WRX that's dumb.
Post away.
