Fast Intentions hi flow cats

SM5654 · 10-20-2010, 12:34 PM

Hello all, I will start by saying I am new to the forum and the world of v6's. I have ordered the FI exhaust and am trying to decide whether or not to get the hi flow cats as well. Couple questions... Has anyone with this system and the hf cats ever had a check engine light come on? And second do the hf cats void my warranty? Thanks for the info guys.

I think it's hit or miss on the CELs. I have ERZ HFC's and no cel so far.

If you are really concerned about warrantee don't get them:

I have the FI resonated HFCs...installed by along w/ FI TDX CBE - and no CELs. Install was done by Tony at FI. In regards to the warranty...if there's ever an issue, I'll switch back to the stocks before taking the car in.

No problem with CEL after 6k miles. I agree to the above, if you ever have problems with the car. Put the stock cats back on. Or get in good with your local Nissan dealership and maybe you'll be ok. I go to my local dealer for everything and they said my parts wont void any warranties
