Basically SLP are straightpipes, is it easier to go this route, or just goto any decent muffler shop and have them whip you up one for cheaper? And anyone know a good muffler shop in AZ?

It should be no more then $100 for a shop to straight pipe the mufflers. Did this to my dads 06 gt vert and its sounds great. Plus it looks sock with the stock tips.

Just get the Slps they have the stamp and look great.

I'd say buy your own tips and have a muffler shop do it. (that's what I did)

Total cost was $85 with 4" stainless rolled slash-cut tips, and I can remove them like an axleback exhaust because I cut the pipe just before the muffler. This way, if I decide to go with a different set of mufflers later, it's as easy as a normal bolt on.

I had the flowmasters before, which I sold on ebay, and thought they were a little too quiet for a performance muffler.

I too have an off road X and you can feel a difference. Just make sure you use the programer to reprogram it with the rear 02's off.

DIY, all the way. Cost me $95, and my axle-back is welded on. I got my tips from Summit, 4" dual-walled with rolled tips. Can't miss an opportunity to share...

That straight pipe set up sounds great. Do you have a clip of a drive by? Is there any drone on the freeway? or around town?

No, I don't have a drive-by clip, sorry. I need to though, I'll put that on my agenda for this weekend. As far as drone, it's quieter than my Magnaflow set up was on my Sentra. The only time I really notice it is when I really get on it. It's fairly quiet at normal highway speeds.
