I add this kit and 6 in angle cut tips to my 2005 Power Stroke. The kit was very easy to install ( about 3-4hrs) and sounds great. Very Loud!! So you might want to keep your muffler on if you dont want it to loud.

Stripping down my new 08 F350- 6.4L Power Stroke. It has been hard to find an exhaust system for my PS and this one looks good and the first one I found with dimentions. I will let you know how it works. Doing the tranny right now then the injectors etc,
