To run cutouts or not run cutouts, that is the question.

I went with the Summit brand partly because i had a $70 gift cert. and the reviews were pretty good. I've only had them a week so I can't speak to longevity.

Also I'm running 2 1/2" exhaust and you're running 3" so I wouldn't guarantee a .2 improvement, but the fun factor is worth it.

here's the latest pic:

Notice how he had to turn one way up into the body? If you don't cut the flange, rotate it, and re-weld it, that's what you're going to end up doing. If not, you have to install one cutout backwards which is what I did. There's no way I could even install mine like that. The kit they send you is made for one side only and yet send you two sets of the same side which is retarded because they won't mirror each other! There's another reason I vote against summit brand.
