Performance Exhaust Option
 

Well the option to add the additional performance exhaust..... worth it or not worth it??? Hmmmmm...... not to much info. on this, no HP/TQ numbers or sound or anything? I am sure most of us will wait for the aftermarket as so will I. Probably will go with the LoudMouth again like I had on my 02.

Now whats got me all worked up are Headers from the factory. I assume this is a Dealer Installation and will be covered under the warranty. If this is the case then sign me up.

yeah i doubt we will get a lot of info on the actual numbers the exhaust will provide for a couple more months

the headers will be covered under warranty if your dealer installs them

It's always worth installing performance parts. :evil:

Yeah I defiantly don't want to be one of the first sets they install. Just don't feel to comfortable with a dealer installing Headers. I wish I could take them to a performance shop.

Would you buy the one from Chevy or another after market company???

Because they would be a warranty item, I expect to get the 'shortys' then custom rest of the way with hi flow cats. That should maximize power from that aspect and give me a distinct tone as well. Nice perc of being in the welding and fab business and a friend with custom exhaust shop.

:word: my thoughts exactly

why doubt the dealer for a header install? it wouldn't be any different then instally an exhaust manifold

I thought I heard once that to be covered under warranty, the dealer must install an item when the car is purchased. This seems pointlessly restrictive and I think it may be wrong. Will dealer installation at any time be covered under warranty?

IMO as long as it is a GM part and a dealer installs it, it is under warranty

correct.

for the money i dont think i'll put it in the gm parts. i have more faith in the aftermarket sources liek kooks headers, as for the shorties why waste the money on shorties jsut wait and spend a few more bucks on longtubes and get a better power gain. just my opinion still not sure what exhaust i'm going with. pretty sure wheels are coming before anything lol

Shorty headers FTL, might as well keep the stock manifolds, you will see minimal gains. If putting longtubes on an LS3 is anything like an LS1 you should see 15-20rwhp.

Shorties will keep the warranty, but also add the least power gains.

Personally, I'd go w/ the long tubes, get the most hp from the deal, and call it a day!
