After owning my Z71 for 5 days, I couldn't resist the urge to do a few mods, so I ordered a Magnaflow 3" cat back and a K&N drop in filter. I've always been a Borla man, but after searching the board, it seemed like most people prefer the Magnaflow. Hopefully I won't be disappointed.

 

Good luck, Next you need a tune. Then you will be hooked.

 

Does the tune make much of a difference if I'm not planning on switching out the cam or porting the heads?

 

Yea the tune will be night and day difference IMO, I think its one of the best mods you can do for the money. I'd reccomend a Nelson tune, I like mine alot but some people have just as good of luck with others. I would go ahead and get a mail order tune though if I were you, you'll be happier with that than a programmer. It might be a problem if you have to take it in for service though.

 

Those were my first 2 mods also. There was a noticeable difference. I also added the UPD tube and lid, that was a pretty nig difference by itself.

 

Be careful,mods can be addictive just read the signature below.

 

Welcome. Congrats on the mods. Once you get them on, its like Whitt said it can become addictive and expensive.

 

don't fool yourself, it WILL become addicting and very expensive the further you continue Oh well if you didnt love it then whater ya here fer.

 

Addicting? No way. BTW Does anybody have a meth injection system they want to sell? I need a fix. My list of mods in my sig. would be longer, but it only allows up to 500 characters.

 

Aint that the truth
