OK I know its been posted over and over but I would like some tips and opinions on aftermarket parts. So far I threw on the injen intakes, stillen oil cooler, and some good hfc's. which are the best options for cat back? which adds the most power etc..... And which mods would you consider next? Im thinking of the lighter pulleys but not sure. Everyones description says theyre product is best yada yada..... I would like actual opinions from actual product owners who has the upgrades installed and knows the power gains. Any help would be great!!!! Thanks again! Oh by the way its a 2009 g37x coupe.

 

Dude, before everyone else jumps on you, search the forum and other sources. A lot of what you are asking can be found in seconds without even using the search function and just browsing the different sections of the forum. Look on youtube for exhaust sound clips. Dyno sheets will show similar results for bolt-on items and what is best is subjective to the individual. Think about your final goal. Is it "Go" or "Show" Our platforms are not the fastest, imo this is due to the weight, but I think is a fun platform to both drive and mod. DO you want low and slow or "streetable" performance. One you have your direction start your mod search/comparison to meet that goal. There is a wealth of information on the forum, but like any other tool, if you are not proactive and learn to use it, then it will not help.

 

forget the 10hp here & there. go straight to FI

 

You might consider a carbon fiber driveshaft.

 

know this is off topic but on avg how much do ppl spend on modding out their G's??

 

Ya I was thinking FI, I looked at gtm and was considering that setup. But wanted to do some other upgrades first.

 

Not sure how much other people do, so far I've put in about 1200.00 looked at some of the gtm setup's and they go for anywhere from 6000 for a turnkey setup to 50000 for theyre 1000hp setup. All depends on the person I suppose.
