I had FRPP shorties and they were great headers, but when I switched I went to LTs. I found some new MAC LTs on Craigslist for 120 and got a new H pipe for 100 so it wasn't a very expensive swap. Install was a little more involved but if you did the stuff in your sig i don't think you'd have much of a problem with it. They do reduce ground clearance a little but unless the car is slammed it shouldn't be much trouble.
