We finally found a donor 5 speed 2008 XB to do our final dyno and test fit before production. The vehicle had a Injen cold air. First of here is a couple pictures of the Cold Air extension, and the header.

The Cold air extension will be available for our Secret Weapon intake.

Here is a picture of the Weapon-R Header installed.


This dyno is Our Secret Weapon Cold air intake compared to the Injen Cold air intake.
3.1HP and 4.4TQ over the Injen.


This dyno is with our header installed and with the Secret Weapon intake.

7.8HP 4.2TQ

Now here is where we wanted to show that the 2008 Scion XB exhaust is very restrictive. As well know there is a large Scuba tank under the vehicle for a resonator.
What we did was run the header with an open exhaust system. Since this vehicle didnt have an exhaust we couldnt test with an exhaust.

Here are our results.


12HP and 4.7TQ. This is at peak levels. But notice the large increase in TQ all across the TQ band.

We will have a small LIMITED Qty. of the headers coming in soon. So we will be posting a sale for those LIMITED ones.

interesting, good job! Id really like to see how much HP a good exhaust without the scuba tank would make. I wonder what it would sound like. Make a midpipe/scuba replacement pipe and Im sure it will sell like hotcakes...

yep that'll be very nice if someone would make one but i guess you'll need to do custom work on it. the gains looks great especially will only bolts on part now can't wait till it become available

 

It would sound like ___ with a midpipe. The scuba tank really helps resonate the exhaust sound.

Nice gains, how much will the header be? Wouldn't mind picking one up.

 

so i guess the s-pipe installed?

i gotta climb underneath and look at the pipe again.....

 

i had the strup header with a full 2.5 exhaust from the header back it was a big diff over stock but not

 

do you have a video clip?
do you have a cat ?

 

search 08 xb exhaust on you tube i had bo resonator just a high flow cat and trd axle back

 

i've check but not sure which one is your's. if you have a link that'll be great and thanx in advance
