Before and after LG Motorsports Long Tube Pro headers

This is a video of my Z06 with the stock exhaust system.

And here it is after the install of LG Motorsports long tube Pro headers. At the same time, I had new E3 plugs put on, MSD ignition wires, new front O2 sensors, and a new fuel filter.

Well apparently I have two error codes set after the header install.

P0153 HC - HO2S Slow Response
P1637 H - Generator L - Terminal Circuit.

I expected something along the lines of a O2 sensor error, but I have NO idea what that Generator error is all about. But since it is a history code, maybe it's just one of those situations where the Z was just trying on the new duds...

The wife and I took it out for a spin today and went out route 375. Pretty wide open out there with very few, if any, speed "obstructions". Some fat slob of a goomba in a white rice-mobile almost pulled out in front of us just because he wasn't looking and my wife gave him one of her GLARES. I thought she gave him the finger, but she says she had ALL her fingers extended.

Anyway, fat head gets up right on my rear bumper and I was getting tired of seeing his fat head in my rear view mirror, so I dropped down into fourth and pressed hard on the go pedal. Connie (my wife) was apparently watching the speedometer and it jumped up there into the high numbers pretty quickly. Fat head was WAY back there somewhere, so I slowed down to a more leisurely pace and let him show me how bad his car was when he finally caught up with me and passed us. Sure showed me, I guess. But at least he wasn't on my rear bumper any longer.

Anyway, the sound of the exhaust is slightly louder then it was at stock, but not unbearably so. It seems much more noticeable at idle where the rumble is much deeper then I am used to. Connie says it isn't bad at all, and I felt she would be more critical of it then I would be. Acceleration seems much crisper then stock and at WOT pickup is noticeable improved.

I had some trepidation using those E3 spark plugs as I couldn't find a whole lot of people who had tried them. But the technology seemed intriguing and I always am one to be interested in new doodads. I do know that idle has smoothed out quite a bit, and a slight stutter from a dead stop is no longer there that I noticed. I suppose a good tune would be in order right now, but at least I don't feel that it is a real pressing issue as well as the Z runs at the moment. And to be honest, I am looking hard at getting my own tuning tool, and just haven't figured out what is best. The handhelds look like they would be easy, but maybe I would regret spending that money when it would be better spent on something like HPTuners or EFILive. But then we get into all kinds of arcane topics like wideband sensors and open loop, etc., which may well be far beyond the level I want to go with this. It's not like I need to shave off a tenth of a second at the quarter mile or anything.

Sounds good, I think i'm going to make the LG plunge when funds allow me.

Where you plan on buying them from? If you buy them from LG Motorsports direct, don't bother talking to anyone except Anthony there. Chris and Bobby were pretty much a waste of my time trying to get info from them about my delayed order. Anthony was out of town doing a couple of back to back races, and those other guys just dropped the ball completely.

Thanks for the advice... I was going to go w/ LG direct but maybe I should just call around and see who has them in stock. If I do go w/ LG direct i'll make sure to talk to Anthony. I just wish I had the money right now. Oh well, guess good things come to those who wait.

LGM has them in stock. The problem was with the Jet Hot coating. First they were a week late sending them off to get coated. Then when the came back they sat around for a while before being scheduled for shipment. Then when UPS supposedly picked them up, the tracking number info said the billing info had been received, but the status never changed. Their story was that UPS screwed up and had to return them to the shop. Maybe, but I kind of doubt it. I have a UPS account and things just don't work that way. They scan the packages at pickup and then every step of the way. My opinion is that they were set in a corner somewhere and just never got picked up at all.

In any event, I think if Anthony had been there the whole time, some delivery time would have gotten shaved off. He did knock down the price some and threw in the gaskets, so work with him when you get close to buying. And try to save up enough for the Jet Hot coating as well. Everyone told me that was the way to go, so that's what I did.

Now if I can just get this new problem with the alternator/generator resolved, I can spend some more time behind the wheel. I'm also working on my Shaner throttle body to put on someday as well. Just doing some slight polishing of the exterior to pretty it up somewhat.

Oh, one other thing. The headers do hang down a bit below the frame. Maybe half inch or so. Bear this in mind if you care is lowered some. Speed bumps may become your enemy.....
