Try going to an online store that has a "shop for your specific car" feature. Put in your car's info and then see what offset mufflers the site wants to sell you...
I jus found out its a 2.25 offset offset, im wanting to put a set of 1 chamber flowmasters but only found ones with center inlet center outlet, could this be made to work?
I just put on the Borla catback and the stock mufflers were offset in center out I believe. Send me an e-mail or a PM. I've got a Dynomax catback system that's brand new I'll give you a good deal on. It's still in the box and has never been installed.
Center in/out can easily be used, it just takes a technician that knows what they are doing. They have to turn the 1 chambers at sort of an angle, but it WILL work. I've seen it many times
