Damn son, is that still snow I see there?? Oh, hell no!!!! Time for that stuff to be way gone!!!!

Anywho, how did you get your governor out of your system??? I like the full revs without the cutout!!!! Want that!!! Do telll....

 

Nice vid BTW....

 

Thanks, The weather here is nice, its April and most of the snow is gone, its mid may when the snow is going away....The rev limiter is removed by HP tuners.

 

its nice to hear the ls4 with out the stupid rev limiter. sounds good!

 

Thanks, I got alot of compliments about how much my exhaust sounds.
Friends say it sounds like Bumble Bee from Transformers

 

So this was just through the exhaust? No cutout? It sounds pretty damn good!

 

Hey williamGT, You know how to tune the VE and MAF tables. Car is running rich with the headers.

 

I don't know how to do that, I got a friend that just took off the rev limiter and disabled the rear o2 sensor.

 

I know how if you have any questions feel free to pm me.

 

Yea I want the rev limiter removed and the DOD. I want V8 full time

 

that can be done with a few key strokes on hptuners. Try to find someone locally that will do it for you. I would if I was near by you.

 

Well come on down!!

 

Nature of flex pipes. The exhaust will accelerate when it comes up on any sort of ribbed/rough surface. That will lead to whistling.

 

I thought it was the flex too. I have a 97 GTP with headers and have no whistling. I know ones a V-6 and a V-8 but the design is basically the same except they do not put a flex pipe on the x-over. I said in an earlier post that I thought the flex should have went on the end/collector part of the headers. I bet that will solve the problem. I am just going to wrap mine until there is a permanemt fix for it.

That is all I have done too. Plus I disabled the COT, since I dont have a cat.

 

wait a second, so you're telling me that the only flex pipe on the system is on the crossover?!?!?!

 

haha, it would be great to get away from this crappy MI weather but I work everyday and have a newborn at home

 

As far as on the headers, yes you are correct sir.........

 

am I the only one that sees this as a problem?

The whole purpose of the flex is to prevent binding in the exhaust as the engine torques. So what's flexing if the rear manifold and the rest of the exhaust are all one solid mount? I might be overreacting as the stock downpipe on my car doesn't have flex but that to me sounds like a leak waiting to happen.
