Depends what you have done and what you're going to have worked on. Obviously a blown non ZL1 car isn't getting an engine replaced with a windowed block. My 2013 GT 5.0 had the transmission rebuilt under warranty with full suspension, tune, full exhaust, short throw shifter etc.. The service managers will try to tell you they can't touch the car, but if you call corporate, they will say take the car in, have the dealer diagnose it. An Autonation service manager tried saying my short throw shifter and tuned caused a synchro failure sight unseen. I actually had another SM prior to the actual rebuild tell me to come pick up the car, they weren't fixing it once it was up on the lift and they saw the LT's. That was before I got smart and started getting corporate involved.

If the mods are the proven cause of failure, you pay the diagnostic and repair charges. If it's not due to mods, they fix it. That was my experience with Ford. I doubt GM corporate would be much different. No experience with a track warranty. That sounds awesome they even do that. Now only if insurance companies would get on board.

I have decided however, that I want to maintain the warranty on my 1LE, as well as maintain a street classification in autocross. This means I basically cannot do any performance mods whatsoever.

This has me considering the ATAK axleback because of the the hype surrounding it, and some of the youtube videos I have seen.

Does anyone have any ACTUAL experience in person with hearing this axleback compared to a stock NPP? Is there an actual difference in volume or tone? In your opinion if no other options are available currently (except for getting an axleback) is it worth the $1600?

Keep in mind that in this specific situation no performance mods are on the table so an oppurtunity cost does not exist except for maybe buying a new set of wheels lol.

ATAK is definitely louder than NPP, by quite a bit, and has a throatier note compared to the NPP, which has a higher pitch raspier note. Ive heard mine side by side with a stock NPP, trust me, you wont miss the stock NPP sound

Quick question about the ATAK? Is it as quiet as the stock NPP on the highway ? I keep my stock NPP in TRACK mode all the time and I like that it is loud when needed (WOT and aggressive driving) but gets quiet while crusing because the NPP valves close back on light throttle. I don't even have to switch to Tour just to make it quiet on longer drives.

I don't have the atak, but I have the Borla s-type which is the middle ground (not quite as loud or high pitched as the atak) and I'll say that it is significantly louder and has a deeper better sounding exhaust note over stock, it really brings the car to life.

I too did not want to void any warranty and wasn't doing it for hp, but I wanted something that was louder and sounded better than the stock NPP, totally worth the money to me because I got all of that plus it is one of the very few systems that don't drone and it can be "turned off" with the NPP valve and when cruising still as quiet as stock NPP.

If you want the GM OEM track warranty coverage the 1LE cars have to remain bone OEM stock other than expendables like tires, brake pads and fluids (provided they meet GM specs). You can get away with wheels and such but when it comes to the drivetrain I asked him about CAI kits and catback kits and he said if you want the track coverage leave it stock.


Now as far as the drivetrain warranty you are fine to run a CAI and catback out on the road on a daily driver, this only relates to those who are taking their 1LE cars and using them on the track on track events and wanting to be covered under the GM track use warranty coverage. GM is the only automaker who is even offering this type of coverage in writing, and there has already been 1 1LE owner who had to use with a total engine loss at the track.

That is EXTREMELY dissapointing.....i get things like longtubes/tune/etc but an axleback or catback exhaust? Come on lol. I bought mine with the intention of leaving stock for a while and tracking the car with a warranty. I was rear ended and got a free Borla S Type catback out of it, guess I never even thought about a set of mufflers voiding a warranty.

Guess its a good thing its a bolt on part. Bolt on, bolt off. If you're worried about warranty work just put the factory exhaust back on.

Don't the Borla systems require cutting of the OEM exhaust?

I thought their axle backs and mid pipes were slip fit over factory pipes.

Axle back hooked up to factory midpipes requires cutting. Catback and midpipes with secondary cat delete will bolt up (to primary cats).

Exactly this. Which is why I did the secondary cat delete from Borla along with the S type rear axle back.

Keep in mind when debating GM's off road (track/drag strip) warranty and how restrictive it is on modifications - they are one of the very few to even give that warranty. Most car makers have explicit language that warranty is voided with any failure that occurs in an off road setting even if the car is still factory stock. I'm not defending GM's position per se - just adding some context to the discussion.

Did you or anyone with the mid pipe and atak series felt like they lost low end power?

Not me. My 0-60 and 1/4th mile times didn't really change, I'm still within the same range i was stock, and i haven't felt any loss on the good ol' butt dyno. i still have the secondary cats tho.

It has no drone on highway and it is quite when in Touring or Sport mode.
Exhaust doesn't bother me one bit on highway - tire road noise and wind noise are louder than exhaust

Nope. Felt the same.
