Hey Fed,
I'm still stock for now. I just bought my car a month ago, and still breaking it in. I'm going to purchase the JB4 in the spring time, and would eventually like to install a downpipe.
I was just feeling out my dealer on how he feels about the downpipe, as I want to keep my warranty. Some dealers I talked to immediately told me warranty will be denied if DP installed. I asked one dealer if I install a DP, and have an engine misfire due to a bad ignition coil, or a water pump starts leaking.....would that cause any issues? Service manager told me warranty will be denied because engine is modified. I argued my point that regardless of downpipe, a stock engine can have a misfire or water pump leak. He would not budge......so I said thank you, and now know to never bring my car to that dealer for any work. That is just being greedy.
It's a shame because that dealer is only 5 minutes from my house. Because of that I bought my car at a different dealer, that seems to have a better attitude, and willing to help the customer. You don't want to support your customers, I'll take my business elsewhere!
