TDF vs Scorpion

What's is the difference, if an any, between the TDF and scorpion systems?

searched but can't find any info on this.

the TDF one if slightly more expensive and built by scorpion but is it to a different spec?

thanks
 
Ok thanks.

i wasn't going to bother with an exhaust for the marginal gains it gives but the trackdays are pretty much finished for the winter so I need to tinker on Ou of boredom so might get one and a remap along with the ktr intake.


on a side note how much is RS tuning charging for remaps?
