ultimate racing downpipe

how would they have tuned this if there is no flashpro tuning for the car? These are more than likely to be numbers as a result of bolting the part on and doing a dyno pull
 
using an aem ems? No clue if they really did though
 
My guess is similar to other down pipe they sell: $275 plus if you want a cat.
 
that wasn't directed to you... you said for them to be emailed. spdandpwr wrote after that asking when it was being released.
 
thank you for posting this - I have yet to see pics of it. Also be aware that this removes both catalytic converters on the car.
So I just reread the description. You have the choice of eliminating both catalytic converters, orrr having 1 high flow catalytic converter added... for $100 or $150 extra
Webby, I wasn't aware that there are two catalytic converters. I thought there was only one at the top of the exhaust pipe right after the exhaust gas exits the engine. Where's the second one :confuzzled:
 
1st cat off the head... #6

----- 2nd one below on the exhaust ... #1

I wonder how many HP gains could come from doing some head work and improving flow from the exhaust side of the head?
I'd be interested to see how the internals of the head look and if there is room for any or much improvement especially seeing as the "header" is internal.
 
it essentially looks like this - except this isn't the 9th
