THere is no brand of premade available, what type of sound do you want?
The stock bents aren't too bad, plenty of room to route actually. I went the race route hahaha 2.5" piping to a xpipe, then ran dual 2.5" lines down to the rear with dual buddy clubs.I am looking at doing the same on my 2010. Space appears to be a challenge. I have not had a really good look at the stock bends in the exhaust yet but the pipe diameter should be fine if it is ~2.5".
What I was planning on doing is running one of those Vibrant Ultra Quiet resonators in front of an 18" Flowmaster HP2. That should be reasonably quiet and tuck up in there just fine.
If I can cut out the old mufflers myself and clamp these in their place, I may do that or go have the local muffler shop weld them in.
