Which catbacks are loudest/quietest?
 

Just curious, I love the sound of my Berk, but how does it rate on the loudness scale compared to other 370Z CBE systems using stock cats?

My CNT catback is about 6/10 for loudness. I am sure with testpipes it would be a bit more louder. From all the videos I have seen, it seems like the GT Haus is the loudest.

What about quietest? I assume stock--->NISMO---> ???

Didn't think you wanted to know about stock.

Based on what I have heard....

Stock being quietest 1/10, Nismo is about 3/10, CNT 6/10 and GT HAUS 10/10.

My AAM Short Tails are about a 6-7/10

Can someone please input where the Fast Intentions and Berk CBE's rank out of 10 compared to others.

Heh I wouldn't give my nismo a 3/10... more like 1.5/10

Add test pipes with short tails and they are an 11/10 :eekdance:

I think the best way to go about this is to get a List of exhausts and list them in order from Loudest to most quiet.

Ie:

GT Haus
Greddy Single
Fast Intentions
Berk
HKS
Invidia
ARK
Nismo
Stock

This is just an example. I would also like to see some input on this as well

This is going to be a tough one, as some of the exhausts also replace the front pipe (y-pipe) and some don't.

I would say Tanabe would be on quieter side, but I couldn't tell you because mine sounds like an angry dragon with LTH's. By themselves I would say at least a 5. With the headers, definitely loud... I would say either 9-10.

What about MXP ? are they louder compare to GT haus?

The MXP is pretty loud, but not Meisterschaft loud. Louder then Fast Intentions.
