Wait wait wait....I just realized I missed something in this thread. The GXP concept had a 3.8 */C in it? I guess that means sawgunner is really the one recreating the concept LOL.

Maybe I read more into this than you meant. Exhaust'* dont "work. They are passive and if the diameter and bends don't create backpressure , they all 'work' the same.

The Corsa exhaust was chosen for the concept'* 3800 instead of the "usual", because they pumped it up to 270HP. The 3800 was switched up to the Northstar which didnt need more than what the normal V8 exhaust vendor provided. GM wasn't cutting corners. They switched the engine and the original engine'* exhaust with its intended role left with it. You keep just skipping by the fact the original motor was changed. You certainly cant fit the original V6 Corsa exhaust on a N* V8.

5 years and a new round of buyers/users does not change a thing. It has the same limitations that have been discussed to death. And you seem prone to bringing it all back without bringing anything new to the table. And I only speak negatively to hearing the same ole same ole. Ya, I get tired of hearing the same ole that leads to nothing.

I would be elated if someone actually discussed something valid about improving performance of the GXP. Still waiting.............Exhaust isn't going to do squat and this whole thread really belongs in the lounge. A FWD Caddy and a GXP are not the same animal just because they both have a N*. And their production number differences make for one to get aftermarket, the other not. You dont need to talk to Corsa to know what you stated, A couple clicks finds me all kinds of Corsa Caddy kits. Cobble (Your negative word for what it does to an exhaust) away with one of them. Kinda defeats the purpose of paying all that money for engineering your gonna take a cutoff wheel to.

Maybe the way I express myself routinely comes off to some as a "ton of bricks" but I am not against valid points, I haven't seen any. Not one. Vague references to this and that. Coulda/woulda/I'll spend the money IF.

As for the way I have done things? At least I have done things. The only things I have found reasonable to improve performance, look, ride/stance. It'* gets hard for someone who actually acts and achieves to listen to woes and what ifs. Bringing up the past that has been extensively talked to death falls dead to my ears. Bring something new to the table. And I'd be all about talking it up. Want an easy 400 ponies in a GXP, an Olds 350/THM425 should slip right in. Now there'* a valid option and something worthy of food for thought. And where I would head if I had a tired N* whose GMPP was used up.

The concept car does not have heated seats? Really?? I like the shiter they put in the GXP too. Plain just looks funny with those seats and vents!

Ok, I understand now:

1) Only discuss mods once you have actually done them.

2) Do not come here to discuss mods if they have been done before, or tried before, just because that is beating the dead horse again.

3) Do not come here to ask questions about mods that have been discussed before, just read quietly and only comment once the mods are done on your car.

4) Certainly do not come here to discuss things you are considering doing, or maybe would like to do, or are just dreaming of doing. This is no place for brainstorming. That is just been tiring, as it has been discussed before.

5) Make sure that whatever you want to comment before you post it will be judged to be a "valid point" by the moderators so to lessen the chances of having to deal with snide comments or pictures/images of dead horses.

6) Certainly don't mention Corsa products in a positive light. It is ok to say that they are overpriced and make no performance difference. Just enjoying the sound of a Corsa system is NOT a good enough reason for talking about one, let alone buying one. Just be prepared for being mocked if that is what you choose.

Wow, consistency is a wonderful thing. I walked away from this place years ago, because of the Admin staff only blessing the "right" way to do mods, and the "right" engine.Since my car of that time was naturally aspirated, my performance plans and mods were not worthy of discussion, nor could the goals that I set for myself have ever been met (and I was told this regularly), even though others did manage it shortly afterward.

Nice to see there is still a "right" approach to modifications here, and more importantly, a "right" and "wrong" way of discussion of those modifications. As I said, consistency is a great thing. Makes it easy for people to know where they stand.

Oh, and Bill, the logistics, shipping etc, are currently being worked out. With any luck my car will be on the dyno rollers within a month. However, I will say nothing more about it, because I have already been told that it can't/isn't going to work, and I don't want to be tiring, after all.

I will state my opinion as I please Mr. Bigerik. If your to thin skinned to debate , dont respond to my posts. We both stated our opinion. When you respond further, so will I. And I guess that brought us to this point. If you feel that'* mocking,....whatever. If you have an opinion as to how I run this Forum I strongly suggest you send it to me, not use the Forum'* Mechanical Sections for your brand of Forum Polity Satire.

Ok.

And just to clarify one point, it certainly wasn't meant as satire. It was just an overview of the comments you have made in this, and other threads, regarding GXP performance mods.

Will gladly take this to PM.

It was nothing ever personal. I just dont want to see the GXP Sections filled with the same things of the past, giving false hope, and reliving alot of research and frustration of the past. I have never stated Nitrous was THE way to go. As a matter of fact, I have cautioned many people many times against doing it if they use the car for family, work, and can't afford the time and expense of a New crate motor. I have also given my suspension efforts a negative view due to longevity and costs. And comparing me to a Staff that ganged up in mass on people, sent demanding PM'* and threats, and gave Admins infractions and bans??? We have opposite opinions on what can be done with an LD8. If I offended you, it wasn't intentional, nor about you personally. It'* about this disagreement. We just disagree and I will be the first to eat my words and hand out plaudits if I'm wrong. But prove me so. I have not closed or censored a single thing you have said, nor brought any of my Staff into it. So please lets keep drama out of it. None of our discussions have ever centered on, or me trying to influence because of my Rank here. I just don't roll that way. Considering your offense to the way I am I will try to curb it. I haven't a real problem with you and don't want this to escalate, or cause you to take this where I prefer it not go.

I see that Erik wants to buy $1500 wheels and a $1200 exhaust, possibly, so why not re-work that money into a new PCM? The 4.4L Northstar provides up to 469 hp and 439 lb-ft of torque! What you should do is either get a new PCM to run that or just get a wrecked 06-09 STS-V and swap in its dash, engine, and transmission. This gives you all of Cadillac'* dash features, full stock PCM so you don't have to tune anything, and a stronger transmission to hold all that power. A dash/PCM/wire harness/engine/transmission swap would be the cheapest way to get to nearly 500 hp.
