I am about to install this set,need some feedback about how loud it would be with NISMO exhaust,any HP gained?

 

What year car do you have? Most '03s won't throw a code, but most '04s will due to updated ECUs i the '04s

 

I got 04 G35 COUPE 6MT. Some guys complained that their lights on,but some did not. I just got confused.

 

I have an 04. Mine stayed on for 200 miles then stayed off. I guess i have an early 04 so i have been plaged by all the other problems...trans,cd player,axles,tire feather etc

 

daddy Z.. ur's went off by itself after going on??? Thats encouraging.. I just got the helix on the other day, and no cel light for 2 days then bam!! It's been on for like 1.5 days... 100ish miles.. I would be stoked if it goes off..

I have an 05' BTW

 

my CEL came on within 10 minutes of installing my test pipes. I ordered some o2 simulators from o2simulators.com, they should be here this Thursday.
