Anyone know if there's a danger to using HFC's like FI or Berk? Will this void a warranty. I have a 2012 G37xS coupe that's 20 months old....Are there any dangers to engine ingestion of deteriorated cats? I don't drive my car in winter. How long are these parts expected to last? Life span? Are gains combined with CAI and a Tune such as an Osiris (UPREV) worth it? Engine VS/&? WHP.... gains....

 

Is there any rasp with the Berk's? I'll get the FI but I really dont wanna wait the 4-6 weeks for them to be made.

 

Why did you revive a thread that died four years ago? There are several recent threads on this subject, specifically the coupe exhaust thread sticked at the top of this forum. Then there are hundreds of threads in the tech/intake and exhaust forum...

 

yeah what he said

 

I think I came off a bit harsh. That wasn't my intent. Sorry if anyone felt that way.

 

Its all good don't worry about it. I found my answer. I just wanted to know if I should pull the trigger on the berk while I wait a lil bit long for the admin intake. Got it.
