Are the resonators available on their own? and if you ask for cats, is it cat and resonator? or just cat?
Based on the above, both are available together?
Also, guys, read what Tony replied with, this exhaust got exactly the same results as the other straight through exhaust, but it was less stressed with the Motordyne (had more power to be made)
Once you're straight through, there isn't much that can be made, it's down to sound type and level, however, as Tony already explained, this car has a very smooth power band, whereas it was lumpy before, indicating this isn't a super stressed tune on this exhaust, whereas it was before with the invidia.
