On the inside it is honestly not bad at all sound wise when your driving normally. WOT is insane though. The sound is much much better with the headers IMO. Much more smooth.
Performance wise it def opened the car up some. 1st and 2nd are completely useless at WOT. 3rd spins for a bit then catches. I also can feel a difference in the top end as well.
As far as why I chose them: I was browsing through the Classified on CorvetteForum and saw a deal on these I just couldn’t pass up. Brand new they are $1300. I got them with 1K miles on them for half the price. : )
The install went VERY smooth. No fitment issues of any kind. Everything just went in like a knife through butter. Me and Smokkin did the install which took us 6 hours, of which only 4 were needed to do the install. We had to make runs to the auto store, lunch, etc.
