No problem - I don't disagree - I'm the same way. I usually don't like to see dyno's or only use them as point of reference anyways....but this system does work man...it really does!

Do diligence is my motto!

Would you be willing to set one up? With some one local? Just have them show up to your shop let them take it to an indi dyno place, and bring it back to you. Or hell if you want to ship one my way I will get a dyno done be4 and after! I am going back to stock this Sunday.

 

That is like the highest reported gains of any exhaust system for the 350z ever. Which makes it the hardest to believe. Making 20whp without high flow cats, test pipes, headers, intake, plenum, etc., and most importantly TUNE (or reflash) is almost beyond belief.

It's almost like you guys didn't reset the ECU before the baseline run, but then you reset it for the new exhaust... or like the car was running rich for baseline and then you brought it back to stoichiometric with the new exhaust... something like that.

Make no mistake though, if the actual claims turn out to be honest and valid within 10-15% of the reported claims, I will jump all over this exhaust. The sound is definitely nice. Actually the sound is rather similar to HKS dual from what I can tell.

Does this exhaust relocate the evap canister?

 

 

Why don't you wait until someone buys the exhaust and posts there own dynos before calling BS? I am.

Because I've seen the same claims before and I have never seen an independent dyno show an exhaust put out 20 HP. It's just physically impossible. You want to tell me that the stock exhaust system on the Z is that RESTRICTIVE? I don't think so.

 

+1 on the diameter

 

I just want some independent dynos done.

 

I want a new design for the exhaust...looks funny on the Z. Yeah the exhaust sounds mean though!

 

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....

if the mrev 5/16 spacer can give rev-up motors THAT much gains w/ just 5/16 of an inch, why is it physically impossible to gain that much power w/ a better flowing exhaust system? you want to tell me that the stock rev-up motor is that RESTRICTIVE?

i understand your skeptical and all, but everything we've stated so far we've been able to back up... from the great looking exhaust to the beautiful sound. we have the dynos that show gains, and independent dynos will probably be up soon as well. afterall, if our cars really were that perfect, who would want aftermarket parts?

 

Ok he clarified the 20 HP gain. I thought that dyno was just the catback exhaust. The 20 HP gain includes removing the stock cat with resonated test pipes which makes more sense. The catback alone according to him put 11 HP on the dyno which is more believable but a little high. I would still like to see independent dyno's just on the catback alone.

 

Makes more sense now. Thanks!

 

I know...when had the chance to go back and read the thread I realized I had not made it clear what 'the system' consisted of.

Thanks for you patience and understanding. As you should know and realize by now - this is not my day job - mostly a hobby - and I'm pretty busy just to begin with...


Rick

 

Here ya go....

First dyno is the stock car vs. the catback.

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

Rick

 

I see that you had testpipes during those soundclips. How does the exhaust sound without testpipes but with stock cats? How much more does it enhance the stock sound without testpipes?

 

The resonated test-pipes actually add some additional low end growl to the system - not much additional howl. You'll hear a little more rumble at idle.

The key to good mufflers is that they are tuned to make this work properly and give you the performance, while allowing the sound waves that are desired to still come through.

Bottom line - the test-pipes do allow more of everything - maybe a 10% increase - so marginal in the consideration.

I hope that answered your question sufficiently.

Rick

 

Thanx for the info. How much louder is it than stock without testpipes? I'm looking for it to be definitely louder than stock in all rpm ranges, but nothing crazy loud. For point of reference, I currently have the injen ses and am looking for something just a small tad quieter, but am fine with it if it is just as loud as the injen. Also, is it available yet through the site, or is there a group buy coming up?

 

Great questions:

It is definitely louder than stock.

Not crazy - but it is called the Fast Intentions Intimidator Series for a reason.

Injen and most others are really loud inside and out - as they drone a bunch too...this doesn't drone, but you do get to hear the exhaust inside the car - so it is much quieter in the car - you wont get a headache from it and you can use your cell phone too!

A group buy is getting ready to be done soon - if you just can't wait - you can call the shop and order one. Jigs and such as still being ramped up and finalized.

Let me know if you need more.

Rick
