Depending on the dyno and your transmission. Jpipe gains around 10whp and jpipe with PCDs is in the 20whp range. Pretty much all modifications are technically illegal. Most states just do a computer test which you should pass without issue. Cali is the one state that you might have to switch back to stock for.What kind of HP do these add? Also, will using one of these allow me to pass state inspection?
Even if it keeps the cat tampering with anything before the cat is technically illegal. I would just keep your jpipe for swapping back to stock its a 20-30 min job.I guess my question is, here in NJ, they read the OBD2 port and they also look under the car to make sure the cat is there..so can I get on of these jpipe that will keep the cat so I can pass inspection?
You would have to make a adapter or something along those lines. If you are looking for power HFPCs are a great options as well.Found a pic, my Ody is to new to me and have not had it on my lift to see under neath. But he is a pic I found on the FB page
Don't know how it fits to the stock exhaust
Sorry about the x car post
No worries. Our HFPCs will work with any Jpipe without any issues. :thmsup:Respect to Richie on the rv6 products!!! My 07' A6-6 sedan will arrive in CA by the end of next week and I'm interested in the rv6 hfpc with j pipe. I'm on the fence about xlr8's jp (no disrespect to Richie) and the rv6 jp. I'd like to know if the rv6 hfpc and xlr8 jpipe bolt up without issue(s)??
