Another 40+ rwhp gain with LG Super Pro Exhaust
2015 8spd auto Z06 arrived today for some power upgrades before digging into the engine. Installed our 1 7/8 Super Pro's, high flows, through stock mufflers and tune.
42 hp at the rear tires and 46 lb-ft with no other changes, through the stock air cleaner.
Next up, pulley change!

No tune - correct? Also, do you have to raise the engine any to get them installed?

Check their thread out for more info!
I think this shows tuning is an important part in the effort to produce HP.
OH, and have a good day!

You know DiabloSport picked up over "50 RWHP On Their Dyno" from a "stock" A8 Z06 at "operating temperature" with their "TUNE" that you can install with anyone of their handheld tuners from the driver seat.
Check their thread out for more info!

OP, your wording is ambiguous. When you say stock mufflers and tune. Do you mean stock mufflers and modified tune, or do you mean stock mufflers and stock tune.

I have always thought that too but could easily be wrong. It does not say "with tune". It says "stock mufflers and tune" which could be read as "stock tune". The OP was not clear as LawrenceFromTorrance also pointed out. Said differently - it could be read as "with stock mufflers and (with) tune" or "with stock mufflers and (stock) tune".
I still have the question.

On my 2014 Z51, ARH mid-pipe headers and Corsa X pipe gained close to 25 HP without having a tune (stayed stock). There was a noticeable difference, esp. in 2d - 4th gear (M7). Don't know how these mods would affect the Z06, but Nick at ARH said the difference between the full length headers and the mid-length on the Z51 was about 10-15 HP at the crank.

I understand why companys do this, they want to sell their headers, still it's disingenuous.
Do you see the LG sticker on the driver's rear quarter window? THAT added about as much HP as the headers.

Nice gain!!
Too bad you guys didn't throw a cold air intake on it before you tuned it.
I'd be curious to see what LG gains with CAIs since they have no stake in the CAI game and I feel their dyno postings are reliable sources.

I agree with some of you guys on this issue.
IMHO! Headers are useless unless you do the whole package. It's not cost effective at all. Anthony stated there were more mods to come (pulley change) so maybe he's logging the parts separately to verify the final outcome. That's a good thing.
I would like to have seen a baseline pull after the header install without an adjusted tune.
And speaking of CAI...........several venders have verified the rwhp increases with just the Stinger RZ installed (and no tune modding required). It's legitimate.

This is from headers AND A TUNE. Now, if they had tuned first, THEN added headers, the gain would be little from the headers. The gain was from the tune. HEADERS are not worth the expense, unless you are going to heavily modify the engine. Sorry, that's the way it is.

This was the very first C7 we did back in October 2013 and the prototype headers. It had a completely stock tune, all we could do at the time was log it, it was another week or so before HP Tuners could get into it.
October 2013 C7 M7 Corvette stock baseline vs LG prototype Long tubes STOCK TUNE NO CHANGES
I know that is not a Z06 but I used that one first because the headers were done and running on the car prior to being able to tune it.
Now the Z06 does react slightly differently without tuning, but most certainly you can gain without changing the tune. This is what we did on our 2015 Z06 M7 car the day after we brought it home. Again STOCK TUNE. I wanted to show the 1st and forth run to show temp differences in the car too, so it wasn't a bone cold run.
Those were our both our own cars so we had done a lot of testing on those, but any customer car will be properly tuned before going home.
Like air pump, the better you can flow air in and out the more efficient and more power it will make

Yes but the exhaust manifolds aren't a major restriction. And your title makes it sound like the headers gave you the gain, when it's the tune mainly.
If you want to properly show the gains from the exhaust you need to change only one thing and show dyno before and after. Not change two things and claim the gain is from just the one.
Back in 2007 a friend and I were modding our Z06's, we added CAI's, headers, and tuned and dyno'd after each mod. On my car we added ARH headers to a previously tuned car and gained 6 peak RWHP, that's it. On my bud's car we put on your super pro exhaust and lost 2 peak RWHP. With a retune we brought the numbers back up but still only gained 4 RWHP, again on a previously tuned car.
IMO those gains are not worth the expense. Now when I went to 12:1 heads and a big cam I'm sure the headers helped, but not on an otherwise stock car.

Good numbers, however, Corsa is claiming 20 additional HP with their cat-back kit alone. With headers and tuning, I would expect a little more than 40... Other vaibles too, like fuel... 93, E85, etc., makes a big difference...
