With the newer cat designs, no reason to delete them either, as they offer little to no restriction, they still filter the raw gas smell, and you don't have to worry about any potential legal ramifications.

That being said, I already had the euro manifolds, so dual made sense.

I suspect I may have gone a little overboard with the 2.5", and that 2.25 might have been more appropriate, but it still has plenty of pull, and if anything the exhaust is a little too throaty when under load.
