I am sure these two things have been discussed on here already but have patience with a newbie joy
From anyone who has tried these two things, do they help?
Thanks

Steve Ruconic (71stagegs) has the front log on his 98.  The stock front exhaust manifold is incredibly restrictive.  He showed me pictures when he did it.  There is no question that it helps.

I haven't tried one, but I'm considering it. People say the rear manifold is almost as good as a header, so most of the improvement is to be found in the front. The cost-to-benefit ratio for the plog is compelling. Considering headers are nearly a grand before installation, and their stage two intercooler is $1100, maybe it is better to go with the plog and intercooler? I don't know, but I'm guessing the plog is the better option unless you are going for the absolute maximum amount of horsepower you can get out of a 3800. Which will cost several thousand dollars, and if you need that much performance maybe you should be thinking about LS-swapping another platform.

Plog is only $150 - I think that's the way I'm going.

I'm not looking for a lot of mods I'm just interested in things that help the stock engine run cooler and perform at its best. Thanks for the feedback

You'll even see performance improve with just porting the stock exhaust manifold (I did).

When I modified my '97 Riv and my dad's '04 GS we did PLOGS on both and same as the other guys, I have no doubt they opened up quite a bit of breathing space. We did a lot of other mods to both cars so it's hard to say the specific improvement but it could not have been a bad thing.

Do you mean the head shield for the throttle body? These M90's and M62's make so much heat I can't see that helping much, but they look neat razz

Yes the throttle body heat shield but now I see the ceramic coated crossover pipe. I imagine that would really make a difference
