Thanks for the input. Wrote hindle and they replied with the following:
The stealth is our street muffler. It has a smaller diameter inner core than the supersport, and so allows for more packing inside, making it quieter, just a little more subdued with the db's. The race muffler is less restrictive with exhaust flow, and may produce about 0.5hp over the stealth. It is about 2-3 decibels louder than the stealth (apx. 5-6 dbs louder than stock).

SInce you can "Only" Use the 2.25" Core Race Muffler on the Step Tube, forget about the Stealth or Super Sports! My understanding was that they burned out the Supersports mufflers in a very Short time during testing! To me, this means that a 1.75" core "IS" Quieter to begin with until all of the core is burned out!

Vince...Do you or anyone know the difference in ponies between the old hindle system and the new stepped system?

Yes, and the answeris 8 more than the standard system which made 12 more! Someone on another site was pissed about no maps and then said that the step system was supposed to produce 20 HP on a stock bike no changes! The "True" story is Hindle said that the new pipe should produce between 6 to 8 more HP than his "Standard" System! Since the Standard System would produce up to 12 more HP and the New system would produce up to 8 Hp more, someone said 20 more than stock! My Bike went from 152.5 to finally 177.5 (so far) HP! Of course I also have the Bear Stacks which are most likely the 5 of the 25 more! My test showed that the Oval Ti 2.25 Muffler was 2 DB Quieter at 6K rpms than my Akrapovic with a CF Oval Muffler! (88 vs. 90)

Thanks vince...I guess 12 additional hp is not too bad...i paid 540.00 to the door for the stealth system..50 dollars a horse is not too bad..i was also told that there is no need to have a power commander for the old system is this true? if i need a power commander will it give me any more horses? also...what are the benefits of a performance air filter i want to get one but i'm a little unsure because when i owned my 2000 zx-9r i was told that the stock filter ran better in that bike than a performance one.

One way to answer your question! Put your bike on a dyno with a sniffer! Make sure that the operator knows how to make a print out showing HP, Torque and A/F Ratio per 1000 rpms up to 12,000! This way you can see "Exactly" where you are rich or lean! If 1000 rpm below and above your "Peak" HP Reading (AND Including peak Hp reading) are "ALL" Below 13.0, then you can gain a few hp (Maybe 2 or 3 more! if your readings are between 12.5 to 13.0) If your readings are between 12.0 and 12.5, you may gain 3 or 4 more, If you are reading 11.5 to 12.0, you may gain 4 or 5 more HP) Get the idea!) Best power, acceleration is around 13.4 to 1! Max power is around 14.0 to 1 but is harder on the engine and my thought is that a lean engine makes the most HP, but does not have enough extra fuel to accelerate! OK!!
