Ok, you'll just have to look at it and hear it for yourself...

semms VERY quite, is it that quiet?

 

Not really as quiet as the audio leads you to believe - a little deceiving - the in car audio is the best representation right now. It was a bit windy and traffic on the adjacent street seemed to drown out the sound a bit - lots of white noise

The guys will do new sound clips on a quiet weekend day or possibly an evening - but they wanted to get something out there as they're getting things rolling.

Broken link for me, anyone else having issues?

Working now.

 

sounds great! Maybe you could test it for db level..just for us california folk.

 

HHEEEEre ya go!!!

Dang! Is that to the wheels? Also where is that shop extreme performance (where the dyno is) located? In the valley?

 

wow exhaust sounds great.......reminds me of fuji

 

Looks like something I would be willing to get if it was less than $1000, anymore and Id just go with HKS.

 

Yep - to the wheels - on the dyno...

They are located in Woodland Hills

 

Never mentioned that the gain was with the catback AND test pipes? Just saw that on the 350z forum and the 20hp increase makes much more sense. Either way that exhaust looks really good. Any closeups of the welds for us?

 

OK - let me make sure we're all on the same page here and make sure again that we have no misconceptions or mis-information - that is the most important thing - We've been completely straight up and honest - and always will be.

1 - We have many dynos of the car, that will be posted over the next few days, from the dyno day - yes it was all done in one day - the car was never removed from the rack or the dyno.

The dynos are of the car with the stock system after ecu reset with stock exhaust, with resonated test pipes and stock catback, with catback and stock cats and with the entire system, as well as a dyno sheet with all of the dyno runs together showing the full comparison.

2 - the posted dyno sheet on the thread from today is the system as described below:

Stock exhaust after ecu reset vs. Fast Intentions complete exhaust system (includes resonated test pipes (with 8" perforated core resonators) and catback exhaust (perforated x-pipe to dual custom designed Sebring manufactured mufflers to dual resonated Sebring tips)

All pipe, including resonated test pipes, is done in 2 1/2" mandrel bent pipe. This is done in house on their own mandrel bending machine.

The catback on the dyno pulled ~11RWHP and the test pipes pulled about ~9RWHP - giving the ~20RWHP gains you see on the dyno - on the BONE STOCK 350Z test car.

Thanks for letting me make sure we're all straight on this....

Here ya go....

First dyno is the stock car vs. the catback.

Second dyno shows stock car vs. catback vs. catback and resonated testpipes.
