Will also have my factory x-pipe, cats and manifolds off my 2011 GrandSport going up for sale as soon as I get them removed. Will post pictures/prices once removed.
Would you be willing to ship the mufflers. I live in Minnesota
Yes I can ship to Minnesota. Would be $700 total to include shipping and paypal fees. I can package tonight and ship tomorrow once payment has been received. Just let me know.
I am looking more into this as I have a 06 and from what I can tell, these are not a direct fit. Requires some modification. Seems 08 NPP are the correct fit and 09 and later things changed. So at this point, I am trying to decide if it is workable. I hate to spend this kind of money if it is going to be more of an effort. But still interested.
Regards.

I was able to remove the rest of my factory exhaust. I laid the factory (2011) x pipe on the floor and then laid the newly purchased x pipe (that was connected to the mufflers I am selling on previous owners car) on top and realized that the pipes or slightly different where they connect to the muffler pipe before axle. My factory (2011) model has slight bends almost identical on both pipes before connecting to muffler pipes. The newly purchased x pipe has slight bed on drivers side but not on passenger side. Upon searching online it appears that is the difference in the 05-08 models and 09-up models.
So it looks like they used pipes from early year (05-08) to create this system. Which means it should bolt up on 05-08 models.
I decided to cut the end off my factory x pipe to work with my 2011 model exhaust that is currently on my car.
This set was apparently built by Jeremy Formato according to the previous seller.
Here is some pictures to show what I am talking about. My 2011 Factory x pipe is on bottom and part of the x pipe that I purchased is on top/left. Notice the slight different on right (passenger side) pipe bend at connection to muffler.
