We decided to modify the Skunk2 header from our car to have a 3" outlet instead of the 2.5".

We used a flare and our 3 bolt flange with the oval bolt holes.

If someone would like to have this done, we charge $150 for parts and labor on this. So if you physically bring us your header, it's $150. If you ship us your header the price would be $150 + the return shipping.

Now on to the pictures!







If you have any questions please let me know.

Regards,

CJ

No comparisons yet. We may have something shortly but we're still pretty busy as of right now so we have to get other items finished first.

We did not test it from 2.5 to 3". We came from a custom 4-1 (that was made for a bigger motor than just 2.4). The skunk2 with 3" did make more power than that but since the header wasn't made specific for that motor it didn't utilize the header to it's full potential.

As far as generally speaking with the 2.5-3" difference. There is maybe a 1-2hp increase over the 2.5" but there's really no where in the band to pin-point the difference.

The 3" is typically made to give your maximum flow when matting to a 3" exhaust.
