Which exhaust makes more power?
 

Nismo owners... I wanted to know if anyone has put on a different exhaust on their car? I wanted to know how much more power the exhaust makes over the standard catback nismo exhaust. The information that I have found from all the exhaust manufacturers only apply to base model 370.

I went with a Fast Intentions exhaust but don't have any dyno numbers that I can provide. I typically go with aftermarket exhausts primarily for the sound. Fast Intentions was exactly what I was looking for. Nismo exhaust was just a little to quiet for me.

Hey Dave, I was thinking of upgrading to FI as well. What options did you go with?

I went with Berk CBE. Amazing sound, amazing quality, and a generous boost in the butt dyno.

The stock Nismo CBE, from Nissan themselves, is listed at only 5 whp. All of the major exhausts available to us run between 14-20 whp (assuming it's your first exhaust mod) or a little less if you've already upgraded to HFCs.

Visually, the Nismo looks great. FI, if you're going for an aggressive look, is tops in that department. Berk has a stock look to it, and I certainly miss the bigger tips of the Nismo CBE.

All said and done, I couldn't be much happier than what I am with the Berk CBE. It completely changed my driving experience, honestly.

18" resonators / stainless

Just had FI installed, along with Berk HFC and NST pulley kit. Car revs more freely now and the increase in power is noticeable at the top.

I just don't understand why these manufacturers of these exhaust haven't put out dyno number for there exhaust on the nismo? They have done it for other cars.

Maybe because the Nismo engine isn't different from a non-Nismo 370Z's engine so the numbers for teh Nismo should be the same as teh non-Nismo 370Z?

Correct, putting an exhaust on a Nismo will probably net equally to slightly smaller numbers because of the more aggressive tune a Nismo already has. Everything else about the cars are the same engine wise, minus the exhaust & tune.

Edit: To answer the main question, I think a lot of Nismo owners are first changing to HFC/RTP to open the exhaust up.

Maybe you aren't getting much response because there are about 30 threads on this topic already. :rolleyes:

Thanks Dreamer....that makes sense.
