I'm looking to do some minor changes to my stock exhaust on my 2013 g37 sedan.

Heres what ive been looking at:
FlowmasterŽ - Scavenger X-Pipe Kit
Berk Technology BT1407-HFC-MET High Flow Cats
Invidia HS09N7ZTPP Test Pipe
Megan Exhaust Resonator Downpipes
OBX Racing Sports Cat Delete Exhaust Test Pipe
Beluga Racing Performance Exhaust Resonated Test Pipes

Please help with suggestions and recommendations

 

Replacement for the OEM catalytic converters:
1. Fast Intentions Resonated High Flow Cats
2. Fast Intentions High Flow Cats
3. Fast Intentions Resonated Test Pipes
4. Fast Intentions Test Pipes
5. Motordyne ART Pipes
6. ARK R-Spec Test Pipes
7. Berk High Flow Cats
8. Z1 High Flow Cats

Between those, I recommend Fast Intentions Resonated High Flow Cats. If you like loudness then the Motordyne ART Pipes.


What exactly do you want for the car? If you want a minor change then an axleback is probably the best choice especially since you are still under warranty and dealers can get **** with replacing the stock OEM catalytic converters.

 

Thanks, I'm looking for a more aggressive sound with some torque and hp gains

 

Does it have to be test pipes? Why not just a catback?

 

I dont want to spend too much money right now. Im trying to keep it around $500

 

Well, I have the Fast Intentions Resonated High Flow Cats and it is probably the best since it produces HP/TQ gains with no rasp at all, but the sound is almost unchanged from stock and the price is over $500.

Maybe you can check axlebacks? What are your goals about modding this car?

 

I want to start small and build up from there. I was looking at these:

Z1 370Z / G37 High Flow Metallic Catalytic Converters

What do you think?

 

Is this what you have?

Fast Intentions

 

check out this thread:

I have the resonated ones. Idk why they are listed for the coupe, but they definitely fit the sedan

Fast Intentions

 

Just got my artpipes in extrmely happy with them low rpms does not feel so blah anymore probably 20%louder then my cbe and stillen gen 3 set up. Not loud at all. Know im really considering some headers. If im able to dyno what my car is now i will post results but low end is definetly more responsive.

 

FI Resonated High Flow CATs are best

 

That was my 1st option , but choose to the artpipe route instead.

 

Thanks for the help

 

Heres a crappy cellphone vid of the artpipes + hks cbe & stillen gen 3 intake. Dont mind the smoke blowing at me either lol

 

Any website recommendations to buy the motordyne art pipes?
