The delta flow is definately the way to go unless you prefer the constant drone in the cab at highway speeds. I haven't put a flowmaster on my truck (yet....but it's just a matter of time) but if I did I would go with the next quieter series "50 Delta" with delta flow. There is very little, if any resonance, they are al little quieter with a nice deep note. Those along with a quality X-pipe will give it that smooth throaty sound that most people look for. It's either that or some 12" glass packs with a shiny chunk of stove pipe hanging out the back.

i installed a volant on my Viper Truck and ran 3 pulls with a stock intake and 3 with the volant. The best performance that the volant showed was a 3hp loss and the worst was 7hp. It sounded kewl but was weak in the numbers. Now remember this was on a Dodge Viper truck so it may perform better in the chevy but by looking at the setup I would bet that you have more Heat Soak with the Volant than you do stock. To me the noisy ass intake intake isn't worth the gains (or losses)

Yeah... buy 2 of them. One to crap on and the other to cover it up.

NO....you do not have to turn on Tow Haul. by loading the Tow Haul software settings this will help (maybe) your truck perform better under tow haul conditions. This is usually the safest and most conservative software setting in a programmer with very minimal gains. For gas engines you will see very little gains in any settings and in my mind are not worth the money paid but that is another topic. Diesels are another story though. Good luck Steve

No, it is not necessary to remove the cats on a typical NOS equipped engine - just make sure your A/F ratio under enrichment is correct. The job of the catalytic converter is to burn any raw/unburnt fuel that has escaped the combustion process, and when you're on the button you're dumping a whole lotta fuel and oxygen into the exhaust system (including more unburnt fuel) and because of the increased oxygen content from NOS injection the converter is guaranteed to combust whatever is left, meaning a spike in converter activity and temperature. Since NOS is usually limited in 10-20 sec doses cat temps normally do not get out of hand. Another factor is wet vs. dry vs. direct port NOS delivery. Dry systems are pretty safe as the NOS and fuel are well mixed and introduced to the combustion chamber in an even fog. The designs of cheaper wet fogger systems are where you can find uneven distribution of NOS and enrichment fuel, and in enough quantity that it can cause serious problems, least of which I guess would be converter failure but I hope you are seeing my point here. If you are going to use NOS get either a dry system or a very professional direct port kit. Whichever system you install make sure you verify proper A/F ratio and reliable system operation. Mr. P. <{POST_SNAPBACK}> I know that I am new here but I am also a long time veteran of nitrous. DO NOT get a dry system. I think Mr P must have just gotten them mixed up but a dry system is the one which relys on the ECU to compensate for the lack of fuel because it does not supply any with the nitrous. Also a dry system is Raw nitrous sprayed before the actual intake which never is distributed evenly to each port which is also another problem becuase the ECU doesn't know which port needs more fuel. It only knows what the the O2 sensor tells it so in most failures the back cylinders are melted down due to a lean condition. Please do your research before actually buying a kit because although many people run it, few know what they r doing and end up with a $35k grenade in their garage. Good luck with whatever u do and remember to do your research. Steve
