I'm thinking about getting some Corsa Clones for my GP when I have the custom catback built. I love these tips on F-Bodies, but always ended up getting catbacks with welded on tips on mine. So, now is a good chance to pick up a set on ebay!
I'm a little concerned that the tips may be too big. Looking for 3" to 3.5" dual tips specifically. The whole system will be reworked and will contain two 2.5" Pypes M-80's. I loved the M-80 on my TBSS when it was stock.
