Again, I’m just the messenger. Therefore, someone would have to go with one of their packages that includes replacing the cam. Okay everyone, start screaming now… LOL

Not gonna lie, headers do make the car loud. However, I have Kooks 1 7/8" with green cats, and they put the car right on the limit of being nice and usable as a street car in tour mode, having a chat with wifey riding shotgun. The cabin is pretty well insulated.

On the other hand, once the supercharger kicks in, the sound of the engine is what will be enjoyed exclusively, which is exactly the way things should be IMO. With the windows down the car is rolling thunder at WOT, while it's a still a purry mildly cammed kitten when driven normally. I think you'll have a similar experience even without a blower/cam.

At the end of the day, I don't regret going with headers.

Headers with hi-flow cats and OEM catback would not be loud. I drove it for over a year.

Your OEM pump will handle the build you've described here.

Install the parts yourself. The headers will require a little more effort so if that is a bit over your head then farm that out. Cost should be around 5-600.00 for install. Then get a remote tune from somebody that knows how to tune gen 5 LT stuff. Since you have a manual it won't be that bad on cost to remote tune since you only need to license the ECM twice. Probably around 500.00 for a tune with the credits.

Add that up...you have enough money left over you could buy JSH X port and still come in under that package. They are selling you stuff you don't "need".

Stock plugs, thermostat, and housing is fine for a bolt-on car. You can put heat shield around the stock wires if need be. You don't need a ATI damper either or a dyno tune for these kind of mods. Bolt-on stuff isn't that hard to sort out with remote tuning.

If it was a heads/cam setup where the VVE is gonna need completely reworked and require more extensive tuning, then yea I would want to be on a dyno to sort out most of the tune. Then verify it on the street.

The above all day. Get a hold of Jannetty Racing and use their remote tune. There is no better way - maybe others as good, but none better.

Good stuff JSH. I’ve also seen where headers + stock exhaust has a good balance of loud plus the benefit of the NPP. As I mentioned, I already have the AWE Touring Catback + resonators + PLP’s (no secondary cats). Needless to say, it’s pretty loud with this setup. I’m nervous that adding headers will make it unbearable. I know, it’s all a preference thing. As well, I was shocked to hear that they said in order to run the Kong X port, it would require a cam due to fueling requirements. I’ve not heard that at all anywhere else. They said the same about E85 (needs a different cam + fuel pumps). If I was to run full E85, yes. But not upwards to E60. Maybe I’m missing something!?

Thanks ARPAD. I appreciate the insight and feedback. This is definitely a big decision.

Sounds like I need to schedule a visit to your place so that we can wrap this up!?!

I bet a lot of it depends on what size lower pulley they put on it, In regards to ethanol percentage. High boost will have higher fuel demands especially on e

HPE made 723 rwhp corrected with mine (and a bunch of other LT4 cars) with 10% lower pulley, OEM high and low side fuel pumps, and untouched virgin OEM SC and TB.

SP750 Parts List:

Yes - ARH Longtube Headers, no - X-Pipe

yes - Roto Fab Big Gulp Intake

No - ATI Dampener

10% lower - ATI Supercharger Overdrive Pulley

No - Brisk Racing Spark Plugs

Yes - Gates HD Supercharger Belt

No - Taylor Spark Plug Wires

No - DEI Wire Boots

Yes - 160 Thermostat

Yes - Billet Thermostat Housing

Yes - Oil Change

Depends - Custom Dyno Tune

Yes - KongX - If you run 91/93, you would not HAVE TO have a new cam, but you would NOT get the most out of your build.

I think I see 100 rwhp (675 corrected) with KongX and the "yesses", which would need a tune.

BTW, his advertised 750 is bhp or 637 wheel.

Ted's package is 100% bolt on plus tune. I'd talk to him about remote tuning. He has tuned my car remotely for years. Anyone, yourself included, if you're fairly mechanically inclined, can install the headers, flex fuel sensor, etc.

Headers are not that loud at all even catless if you do dual resonators before the stock NPP muffler. My brother has this setup on his ZL1 and it's actually quieter then my stock Header, no cats, Borla 60608 resonated X, Corsa NPP setup.

from everything i've learned they are right on point. They are in the safe limits of your stock fuel system on 93 octane. You could get a DSX boost pump and do a little E85 mix but why at that point. E85 mix is just a hassle. You could do a little blower work and not run as much boost also but why. I believe they gave you good advise about running out of fuel. You can always add to the build later.

Why is mixing e85 a hassle? Just keep some E85 in the garage and fill when needed. Takes me a few extra minutes to mix and fill my tank. I'm either on target or within 1-2 points. At the station I just use my calc and it literally takes as long as swiping your card again and putting the hose in....



Plus the fact that i can make +45 hp more on E35-40. If you can run it and have access to ethanol there's no argument not to run it.


I paid $4.20/gal of E85 last night, compared to $6.29 for 93.

E85 is $3.79 near me. How does your mpg compare on e85?

At his power level, we should ask about the percentage of time spent at WOT, too My fuel economy is 20-25% worse when using E50.
