What headers for my corsa touring?

[cjweb11]

2007 Z71 5.3L just got the corsa touring in and looking for advise on header options
Thanks

I've been looking at kooks for mine 2011.
But I haven't read anything about them tho. I have noticed they don't make a y pipe for the 5.3

First and foremost.. Make sure you get high flow cats. DO NOT go catless. Trust me. Had touring without cats and it was extremely raspy.

Look into dynatech. Probably the best bang for the buck for a total header/y-pipe package.

Thanks for the info that helps a lot, I do plan on using cats and am aiming for long tubes, that dynatech setup looks pretty good, that is also the only long tube setup I've seen with a catted y-pipe to match

Am I missing something (likely) or are there not many other long tube muffler-forward setups like the dynatech out there?

 

[THE YETI]

There are a few. American Racing, stainless works.

You definetly need long tubes. Anything else would hurt more than help.

 

[cjweb11]

I will look into those as well, thanks. I have read a few "shortys are bad" type posts, what is the story there?

 

[THE YETI]

They just aren't beneficial for LS based engines.

american racing 1 3/4 they have a 3 inch catted y pipe. Ive been installing these on the suvs takes about 3 hours install very easy. Im getting 1 7/8 for my escalade

Thanks that was my next question about one with 3" collector and Y-pipe, I'm pretty much sold on ARH
they only come in stainless, do u usually have them ceramic coated? I'm thinking ill go ahead and fork the cash over for it but would like y'all's thoughts

 

[NORCAL SS]

i dont have my ctsv coated and has less space and i run their headers. If you want to do it go for it but honestly id just slap em in.

 

[THE YETI]

You don't need them coated. You could, but it's not going to make or break you.

Mine were straight stainless. They'll discolor a little from the heat.

 

[cjweb11]

Sounds good thanks guys, heres one guys take on why he doesn't do coatings and an interesting tid-bit on collector design (info which I'm sure you 2 are already aware of)

This is the correct part from ARH for my 2007 5.3L 4x4 Tahoe application, correct?
GMT0734

LMPerformance only shows compatibilty with 07-09 Silverado/Sierra 1500/2500 (Not HD)

Fastlane Turbo also shows compatibility with 07-11 Tahoe (2wd)

Probably over ANALyzing Just making sure it is indeed going to fit, function, etc.

 

[THE YETI]

Best bet is to just call them.

 

[cjweb11]

Thanks for all the help, gave arh a call they confirmed the GMT0734W/C is good to go for the tahoes as well. looks like it's time to spend some more hard earned greenbacks

Well how do you like them? I have the dyno techs

 

[cjweb11]

Unfortunately I havent even placed the order yet... haha
I finally got around to installing the corsa touring on the stock headers in the driveway last weekend, which I am very happy with by themselves, nice low growl at idle and roars when you open it up, hear a slight difference in exhaust sound while driving, but no hollow drone whatsoever, maybe just a placebo effect but i swear i feel a little more get-up-and-go out of the hoe.

I'll follow up as soon as I get the headers done.
For now heres some pics with the catback:

cjweb11, did you ever get those headers?
