Newbie with questions!
Well, I finally found the car I've been looking for-2000 GS4 in white/ivory with Premium package (Nak. etc.) with extremely low miles in showroom condition (more about this later). I pick it up tomorrow! 
I have learned so much from all of you at CL and really appreciate it. I have a couple of questions about my first mods:
1. I am considering the RMM exhaust. I heard it on their website and it sounds great-not too loud. Any personal experiences with this exhaust? How's the real world sound and the quality? Any other recommendations?
2. For those with different width wheels front/rear in either 18 0r 19" - I assume you can't rotate your tires every 5k miles. Has this been a problem with tire wear etc.?
Also, what is the correct rim offset and width for both 18s and 19s? Also tire size for both-I will be lowering the car eventually on coilovers of some type and I cannot tolerate any tire rubbing!
Thanks in advance for any advice! (Just realized I may have to change my username
)

future,
welcome to CL and congrats on the new car.
the RMM exhaust is pretty popular, so are the Borla, L-Tuned and Blitz to name a few. The biggest issue with the exhaust is the drone you'll get at 2k RPM, you need to be aware of it with all of the aftermarket exhausts it's there, but as long as you don't mind it you'll be happy with any of those above. Also, I should mention there is a thread about the exhaust hanger system, I personally can't stand the "cheapness" of the hanger system on my Borla, but that is compared to stock which is "bullet-proof", The L-Tuned is the same as stock. I have no experience with the other aftermarket hanger systems. See if you can hookup with someone on CL in your area to listen to exhausts, maybe at an upcoming meet if you are still unsure which exhaust you want.
If you go to 18-19 you will probably experience greeater treadwear than the 16", but not likely any worse than the 17". Offset will vary based on rim design, but a general rule I think was +38mm-+45MM works on most wheels for the GS, but again that will depend on widths and styles...you may want to consider big brake upgrade possibilties as you shop for rims - just take your time and do it right.
Lots of luck with the car!

Congrats on your future purchase!!!!
I don't mean to thread jack but is the RMM exhaust piping bigger compared to stock? what is the stock piping dimension? From what I remember, the stock system is pretty good quality with mandrel bends... What is proper/efficient size piping for a 400?

After my initial post, I read the thread about exhaust systems in the engine forum-very helpful. I have been modding cars for many years-actually everyone except my '94 ES300 a few years ago. I am looking forward to doing this car.
Do most people go with larger rear tires/wheels than fronts on the GS? I realize that on a rear wheel drive, it looks good and serves a valid purpose as well. If so, any advice on the correct tire size for 18" wheels and the wheel width? I am thinking of Volk LE37-K in 18x8 and 18x9.

I would go 8.5 x 9.5 if you can. You can then fit comfortably a 245/275 combo which is pretty standard.

I have the Lexus "L-tuned" OZ Salina wheels, and Lexus set it up at 18x8 in front and 18.9.5 in back so if ur looking to do what lexus recommends ...go with those sizes. ... but again WELCOME TO THE CLUB!

So you know when my tires need replacement, I am going 245/275.

I have these wheels too and the one thing I did not like was that Lexus did not go with 8.5. That's why they are running the 235/265 combo, a little small IMO. With the 9.5 rear, 275 is fine. With the 8 front, 245s will fit some wheels. When I emailed L-Tuned, they took the safe route and said not to use 245s in the front. When the TTE sports edition in Europe came out using these wheels, guess what was on it: 245.
