Hey,
I just bought an '06 M6 G35 coupe. Car is amazing!

I plan on doing atleast a cat-back and an intake. I know nothing about these cars right now. I come from a GM backround and am new to foreign cars. I'm sure it has been asked plenty, but the search feature never seems to give me what I'm looking for. I just find threads that say "do a search".

I'm looking for a nice sounding cat-back and intake combination. Also, if there are any other "simple" mods to do, like the intake plenum spacer (I think?). Again, I know very little about these cars and the best bang for the buck type mods.

I want to keep my warranty valid, so I'm not looking for anything major. Just to clean up the airflow to and from the engine. Might go with headers down the road, but for now I think a cat-back is all I'll do to the exhaust.

Thanks to any and all who reply with useful information!!!

 

Cat backs don't really add much on G's or at least on the Non Rev up's, the cheapest mods have given me the most power, according to the dyno,

Sun Auto Hyper voltage system 178 buck 10hp/13ftlbs of tq
New lower plenium and spacer 600 bucks 15-20 hp (so the company says)
those are to of the cheap things, but if u want some headers i've got mine for sale cause im going Cali and i need cats, so and i do have the sound clip

 

Thanks for the reply. The cat-back idea is more for the sound than adding power. These cars are too quiet stock, imo.

What is a Non-Rev Up? I guess I have the Rev Up engine? Its an '06 and says "REV" in between my tach and speedo...I don't know what this whole Rev Up thing is...???

What does the Sun Auto Hyper voltage system do for the car?

I don't need the headers right now, that'll be a long ways down the road if I choose to do so. You'll need to get rid of those headers for your APS turbo anyways...

 

The rev Up motor from 05 or newer coupes, and had an adjustible shift light and more power im not sure, what infiniti did differnt in terms of tuning or anything like that, but the hyper voltage system ups your cars voltage to a steady voltage i think 15-16 volts there for a stronger spark, it works like a capactier does so, i hope that answers your question

 

Thank you, very good information! Will any of these "mods" void my warranty?

Anyone else have any opinions/suggestions?
