Hi all
Full decat, single, jspec
I've just changed my TRD cat-back for a HKS Silent Hi power exhaust and now suffering from overboost up to 1.67bar.
When I stripped out the TRD there was no sign of a RR from cat-back and have now stripped the whole system and still no RR so I want to put one in.
IIRC it needs to go close to the turbo as in 1st decat, but my problem is I have a custom 3" downpipe with a section of Flexi-hose at the end.
My question is : Will placing the RR here be detrimental to the integrity of the Flexi-hose with the added resistance/back pressure or should/can I place the RR further down to 2nd decat and still be efficient?
Just to add, there' s no leaks, wastegate or otherwise.
TIA
Mike
