Header question???
So I came up with pics and finally saw the oem headers and came to realize that the headers give us power mostly because the desing its kind of restrictive but the most important thing is that the header desing eliminates two of the four cats on the car , my question is simple Iknow just with the headers the car wont be as loud and it shoul gain from 25 to 30whp, is theres a product that can let you remove the other cats and leave the oem cat back? if so wich is it ? anyone knows power gains on this , or is the only way to doit is by removing vthe cats on a muffler shop? will this throw a cel, how much power , drone ,noise w this set up? ayone this is what i wish to do with my car but dont know if it is worth it dont want to be loud what so ever
The restrictive nature of cats mutes the exhaust a bit. So when you remove cats, the exhaust will be louder.
I think HKS has just a mid-pipe which would remove those cats and still leave the stock exhaust in the rear. That's the only one I'm aware of.
Do a search for Sikky and PPE headers here and you'll find a ton of threads, and lots of videos to give you an idea on sound, issues with CELs, etc..

The headers and exhaust work much better as a combo. I don't think headers will be as effective going through that restrictive OEM exhaust. Removing the exhaust cats wont throw a cell. You will definetely have more drone and a wiff of gas now and then. An option is having your headers installed with high flow cats and then using an aftermarket exhaust like the Joe-Z. Thats what i did...
