Default Dynograph: bone stock vs T1R exhaust w/o testpipe


Thanks to AJ-Racing for great product and Chayen and JL for setting up the dyno day.

The stock dyno was done at october, 2004 while the dyno with T1R exhaust was done yesturday. 8whp increase without the testpipe.

For a better comparison, you should dyno on a day where all atmospheric conditions are equal (aka, same day).

Nice gains though.

I agree, the atmospheric conditions are fairly different.

15 degree F temp difference and .2" mercury...which is enough to see SOME difference.

However, regardless of the atmosphere, these are nice gains for just a cat back

I understand the atmospheric conditions plays an important part in the results of dyno. However, I didn't have a chance to dyno with different setups at the same time.

Hence the different CFs.

And the T1R SS indeed offers excellent gains.
