I have Pypes 2.5" on my car. Love them. They went on without any bending or banging.
Like bogie87 says, "love the sound of them." Was debating getting 3" Pypes. Listened to my firends and now, no regrets.
Pypes offers 3 mufflers options for the kit. I don't know which they sent (got em through a local shop) but the mufflers are straight through. I can see unristricted daylight through them.
Enjoy
