first thing, do they make any difference in sound? Second, which ones are the best to buy? Third, what would be an expected number for power increases? And last one, are they difficult to install? I hope someone can answer these questions for me, and by the way its for a 2000 tiburon. I know its alot of questions, but it would be a great help. Thanks.

 

sound? maybe louder if you have a CAI.

do bother, nither of them will do veyr much without the other.

on a stock ssytem? maybe 6 hp if that? But its increase gets bigger as you do more things. cams, and so forth.

I did the BIM and BTB after CAI. I knew veyr little. I thought it was easy, just took time. Its just a bolt off bolt on job.
