Im wondering if i need to tune right when i get the DP or can i drive around for a couple of weeks untuned? its a catless DP with electric cutout, from hahn
like Rob said... you will be fine... you will sound better too 
I am running a catless Hahn DP and full exhaust with no tune yet.. had them around from my last SS... although i will be tuned by spring..

The HAHN Catless is great. I would suggest buying a cheap code reader/clearer though, cuz its not an, IF, but, WHEN, it throws a code.(both O2 related) P0141, and P2196. They will not affect/effect performance but will cause the remote start not to work.
Hey Peev... change that sig! I know you miss the blue one

i dont have remote start, i have a 5-speed, well good, so im going to order it next week when i get my next paycheck so i feel a little better about dropping the money. i work at a chevy dealership so i have many code readers at my disposal so i can clear codes when ever.
i was going to order it today, to find that my debit card was missing! so another week or 2 for them to send me a new card, then i can be as loud as you rob, but you aint got no train horn!!
Its a good purchase, i put mine on like a month ago, I love it!! No codes, knock on wood. I also work at a dealership, makes life easier. took me like 20mins to take the cat off and install the DP. sounds sweet on cold start up and when you put the hammer down. can't go wrong.
