Firstly, I am very sorry if the questions I am asking have already been asked and answered. I've been lurking for a while and I'm unable to find definite answers. Thank you for looking and trying to help.
First, I live in Washington state and am unsure of the emission requirements and tests required for diesels, if someone could enlighten me on these, I would be very grateful.
Second, I am looking to do a couple modifications to my car and have a few questions that pertain to those specific modifications:
I am interested in modifying the exhaust, I realize that straight pipes are the more popular option, but I just want something that will make me excited when I pop into the higher rpms. I'm somewhat hesitant to modify it though, due to not knowing the specific regulations in Washington state for Catalytic converters/dpf.
That said, I have heard that simply popping off the exhaust manifold and replacing that is pointless, because the stock exhaust manifold doesn't really even have a use as the exhaust is already completely muffled by the time it gets there.
Now, In a perfect world, I would love a straight pipe to either a magnaflow or flowmaster. Any ideas on that?
Now, I have seen that there are actually quite a few different companies to choose from in this area, and it looks like the most popular are Unitronic, Kerma, and Rocket Chip. I have read a lot and would love a Unitronic stage 1+ chip, but am again hesitant, because people have complained of boost creeping up and of the chip over powering the car and causing damage (as of right now, the car is stock w/~60k miles). Would Stage 1 be a better choice in the long run?
- Related to both exhaust and chip:
I had read that Unitronic was adding an option for a dpf delete, can anyone confirm this?
Thank you for looking and for any help you can offer.
EDIT: Read more about DPF delete and it's a no no in any state oh well.
New question: I read somewhere that there are 2 catalytic converters in my car. 1 standalone cat and one actually inside the dpf, is this the case? also, does anyone have a diagram detailing the parts of the stock exhaust? Thanks again!
