I'm looking for something that sounds good but I want the best hp and tq gains. LTs and o/r H? X? Midlength? Shortys? What brand? I currently have the stock exhaust.
Well, im not an exhaust pro or anything, just going by what I've read on these forums. I hear X's give better gains than H's. About the headers I don't know.
Go with LTs if you're going with headers. As for mid-pipe, I like the Pro-chamber, but I'm not sure on fitment with anything other than Mac headers. Cat-back is pretty much your choice.
If you want the best gains go with Borla, magnaflow is right behind Borla in best performance. Put it with an O/R X-pipe for the best gains from your mid-pipe and get LT headers. That combination will give you the best performance gains for your exhaust. I'm not sure how good that will sound. I love the sound of Borla's but with the X-pipe I'm not sure.
go with x-pipes. as for a brand ... i would say the complete bassani system from headers back to mufflers. it's a bit pricey but it sounds soooooo sweet.
