I feel like this is one of those noob type questions where people will answer by pointing out 5 different threads that answer my question. I've searched and I'll ask anyways.
I am shopping for a DP and UP. Which should I buy? Should I be shopping on price only or is there some compelling reason to buy one (Cobb, Invidia, HKS, etc.) over another? I see catted DP's from ~$480-$580. I'd prefer to have the best rather than save $100 when it comes down to it. But if it's all the same I'll spend the $480. My LGT is an '05 MT w/ SPT intake and cat-back, BTW. Thanks.
