Do you know roughly how long the ST170 flexpipe is?
As far as i can tell if i put just the ST170 manifold theres only going to be around a 10-12 inch gap between the bottom of the manifold joining to the the rest of the system. I want to either put the ST flexpipe in it if it will fit nicely or weld a peice in until i cant get the rest of the system sorted.
Again thanks and if you have any info that might help with what i just said let me know.

Tbh m8 you can pick up the std st170 cat which is a sports cat 2nd hand for the same prive you will pay for a decat so in my opinion i wud say it was worth the risk. Also some people who have st170's say they actually have lost power?!?
Not sure on the sizes m8 as now it is all fitted to my car and its not the weather for checking lol. If you fit the cat/decat and then the flexi from the the st170 it will be the rite length to meet you std catback system
