Not worth wasting your money if you are in CA.
Other than a good cat back, most exhaust mods don't open up too much power. You can invest in other things and see better results if you are looking to increase the 'fun' factor for your car.

 

Grab a tuner, and a k&n drop in filter and a set of gears, you will make the car a lot peppier and still pass emissions and inspection in California.

 

NO - you will not pass visual without all 4 cats. Like said before you can do alot of other things to have fun with the car. If your looking for basic stuff look into CAI (make sure they are CARB legal), UDP, gears, posi, tune and j-mod (if auto), any list of suspention mods. If you want more power and have a few grand then look at a turbo.

It's cheaper, gives the same gains and 50 state legal to drop in a k&n filter.

 

yeah not gonna get them just gonna do X-pipe w/exit front of rear tires, tryed tuners think they work best for auto trans more then manual trans. the preset 87 octane-predator dragged my engine. but i agree on every thing else have most of it

 

Good luck with that, you will fail visual inspection.

 

with the x-pipe set up? ive seen a few pass, but ill look in to it, now a days since the ARB got stricter im more puzzle on building my car... dragging my feet
