So I was doing some research on installing the stock GTR exhaust on a G35 coupe and I just have a few questions that I couldn't find answers to.
1. Do you need to tune the car afterwards.
2. How easy is it to get to fit.
3. Any issues with it afterwards such as droning or loss of hp or torque?

My reasoning to get this done is mostly for the aesthetics and not performance, so just doing some research before I attempt to find a shop in SoCal that is capable of doing this but don't want to harm the car in any way. Thanks.

 

I had a gtr exhaust installed on my g with the tips about a month ago. I haven't gotten it tuned and I see no performance problems but I do think my mpg went down about 2mpg. Also it drones like between 2-3k rpm. It can be really annoying when talking. Im looking into having a branch resonator installed to fix this but im not sure if that will even work.

 

& its not easy to fit it requires alot of welding good welders and your rear valence will have to be cut

 

Cause I was originally going back and forth for the HKS or x02, I honestly don't know exactly what drone sounds like as I've never bought non reputable branded exhausts before but but reading it's like 50/50 between those two even.

 

Yea this was my first "aftermarket" exhaust. I have no clue what the others would sound like but if drone is a deciding factor for you I would say DON'T get it. It's gonna be expensive in the first place and then you're gonna spend more trying to quiet it down.

 

Drone is more than a sound. Its a sound and a feeling. It is the most annoying noise to the point that it feels like its putting pressure on your eardrums. You don't want it.
