I'm considering a set of Texas speed 1 7/8 headers. But after thinking about the yearly emissions check and overall install I was wondering if cat deletes would be a better choice. Can someone tell me if there's a huge difference going with long tubes vs deletes? Also for the yearly emissions check it would be easy to remove deletes and bolt in the cats.
Does anyone make a midpipe x like the borla 60606 that deletes the cats and bolts directly to the factory shortys? The 60606 only deletes the secondary cats.
Appreciate any input.

Sounds like your best bet would be LTs with green cats.

Deleting the factory cats will remove some heat, but would require a tune, voiding your warranty. If you're getting nitpicky, the tune with or without the factory cats will result in about the same amount of rwhp pickup. In other words, the rwhp gain beyond the tune, comes from the headers.

My suggestion, would be a tune with the factory cats in place, with the secondary cats deleted with the Borla Pipe.

Typically a tuned car vs a tuned car with headers is the difference between 25 - 35 rwhp.

Again, not sure if you're looking for sound, removing heat or cheaper rwhp so given you my best advice from a "how can I make the most power for the least amount of money perspective".

The difference between headers and cat delete pipes will be minor on a stock car. The more you mod however the more it will grow. I would do it right and get headers up front.
