If I put a full exhaust on my GT..L/T headers, midpipe no cats, and catback, do I have to get a tune or could you drive it as is. The reason I ask, is I'm planing on added some more parts this summer that will require a tune, and I dont want to pay for a dyno tune twice, or waste money on one of those hand held tuners. Opinions????

 

yea i'd get one. dybo tune is best though

 

The rear o2's will throw a code without. Get a Sniper Tuner and then you can change the tune yourself as you add mods.

 

no you will not need a tune you could either get a tuner to turn off the rear 02s or get mill eliminators

 

Very good idea

 

Would it be ok to drive though for awhile without a tune...I'm planning on getting the full exhaust, then maybe a month or two later a procharger. I don't want to buy a tuner for 300 bucks or get a dyno tune if i don't have to, it will just be wasted money since I will be getting a dyno tune for the procharger. I just really concerned with doing damage to the car without a tune (don't see how that's possible with just an exhaust), but I was just checking.

 

you will need a tuner once you get it dynoed go to the place that you want to dyno it for you and buy a tuner that they use so that way you have it before hand

 

you dont need a tune for full exahust really. it would help but you dont need it.

 

+1 you'll be fine

 

some guy on here i tihnk, his car ran really lean or rich ( cant remember) after he did the LTs
