I had the K&N FIPK Cold Air Intake installed in mine although I don't know whether I got any performance gain out of it (but it sure does feel like it did) without actually getting it dyno, but from my experience (I have never used any other CAI other than K&N on any vehicle I owned) I have never been disappointed. I have also never encounter any MAF or sensor issues.

 

BTW, Richard, are you planning of installing headers in the near future? Just curious. Where did you purchase your Magnaflow exhaust? and if you don't mind, what did it cost you? to include shipping charge, if shipped.

Thx, Dan

 

Hi Dan

Actually... I am planning on doing the duramax conversion next year with predator. As for the exhaust, I had the magnaflow muffler patched into the existing pipe for $350. My pipe was in perfect condition.

 

That's awesome, I want to go that route one day. The last gun show I went to I parked behind a 2 with a Duramax from Canada. I wanted to chat with the owner but they were gone by the time we left.

Can't wait to see the pics!
