My R2C is in the mail. Now time for exhaust and a possible tune. Do I need a tune if I am not doing HFCs? Also, I was thinking of invidia gemini for exhaust, but have recently found threads that it isn't a quality product, any comments on this? Also, how about the hypertech tune, would that be good enough for intake/exhaust? Does it actually help at all with shifts. Can't seem to find good information on the Hypertech. \


On a related matter, who has the lower price for the eibach springs and what can I expect for installation cost? Thanks in advance.

 

How loud do you want your exhaust? How much are you willing to spend? Sedan or coupe? AWD or RWD?

 

2011 g37s coupe. Don't want to be that loud, just want the performance gains and louder than stock but no drone in the cab. Also don't want to go above $1k if possible. Would like to buy used, but not many locals are selling (Charlotte, NC).

 

i'm on the same boat..just got a 2008 g37 coupe with the sports package.def going to get the r2c intake first and then thinking hypertech programmer then exhaust.is the hypertech worth it?

 

Dont waste your money on HYPERTECH, ive heard its garbage, but thts just my 2 cents

 

I like my Gemini.. Ive had it on for 1 month now, so not too long but no problems. I've heard bad things about their flex pipes, but I have'nt noticed anything yet. Anyways its a cheap fix if so. Sounds great, not too loud and no rasp. I would recommend it as a good exhaust.
