full delkevic exhaust

[outback_imp]

The one I installed definitely needed at the very least a PCV to see the power gains the exhaust is intended to give. The bike may *work* fine without the PCV or retune, but you won't see near the benefits without that. It's also important to mention that if you open up the exhaust, you need to open up the other end too. Open up your air intake . More air, more fuel, faster flow, better go.

for example, when i installed my decat headers and can, i also removed the air snorkel, widened the intake bells, and installed a PCV to adjust the fueling (with a map specifically designed to accomodate the changes i'd made). The results were significant, but you can tell that I could get more out of the bike with the right equipment. a PCV is kind of an "approximate" solution. my fueling is maybe 90% as perfect as it could be for my setup. If i also used the dynojet O2 sensor autotune system, i'd be even better off.

However, if all you want is gnarly noise, no you don't need a tune or a PCV.

Thanks for the info and help, I did plan on installing the tsr funnel in the side of the airbox to give it a little more air to go with the exhaust. bought one on ebay but never got it and finally got a refund.
