Hey,
I was looking around and can not seen to find any valve body transmission upgrade kits for the GS400's. Anyone know of any? Cars just stock, on my list in preparing for installing of additional upgrades.

Also what exhaust seems to do the best, I have read so much. I will be installing an SLD for sure, want it to flow well.

Thanks for any imput.

La400,

I'd like to introduce you to the search engine on ClubLexus. It's the most powerful tool and will let you find answers to 95% of the questions you'll have immediately.

Search for 'valve body upgrade' in the GS forum (a bit of advise, I wouldn't do this upgrade unless you have a turbo or supercharger... it's not needed IMO until then):

among others...

For exhaust there are MANY options and considerations...
- specs (muffler only, catback, ...)
- fitment issues
- drone
- loudness/noise
- power gain (dynos if possible)
- pics (by itself and on stock car if possible for comparison)

Start with the Norcal exhaust competition video, although they have no Borla in it

I think it's supposed to be LSD.
