looking to add some hp and not spend alot of money. notice most people assume dropping the cats will increase hp. is it not true that in some cases it actually decreases hp? i am currently stock w/o mufflers and figure maybe leaving some backpressure is good... about cams, i was wondering people's opinions on which cam would give the most performance gain with a stock vehicle...is there one available that would not require other mods and/or a tune? what could you expect as far as rwhp?
