Downpipe

oma3710 · 08-10-2018, 06:46 PM

I've been doing research about downpipes. Seems like the only way not to get a cel is going with a catted one. I'm leaning towards vrsf because it has great reviews and it's reasonably priced. I've read that the downpipe fix doesn't work but the jb4 clears the code. Jb4 isn't an option for me because I already have dinan stage 2. My car has 100k mike warranty so I don't want to have issues with that. Do the spark plug non fowlers work? How many are using them with no issues?

If you've been doing research you wouldn't have needed to create yet another thread asking the same thing all the other threads asked. You answer is in the forums if you'd just scroll down a few posts here

Our DP does not get CELs. When you go with a less expensive catted dp you can get more issues. HJS cats are the best!

We need a group purchase on the dp's. Or do they go on sale on Black Friday? I'm in the market for one too.
