To make it is brief as possible, I've had two experiences with Perrin, both of which have been negative. Years ago I purchased an uppipe manufactured or labeled by Perrin. The flex joint they use has a pension for leaking/screeching under boost.
Fast forward to today and my 08 STi. I purchased their catback and was pleased overall with the design. In the end though, they provide their product with another flex joint at the catalytic converter flange. I stuck with my stock downpipe and after having tried numerous different configurations (including the suggested method from the instructions), there is still a leaking/screeching noise.
Myself and another member have tried to work out the problem with Perrin, but for me, they have yet to return a phone call. Numerous attempts, numerous failures. Period. Emails? WHEN they respond, they basically point to user error and dont offer any other suggestions to fix the problem.
In the end, Perrin gets two HUGE
for their service and taking that into account, one
for the product. I whole heartedly would not reccomend Perrin to anyone....maybe my worst enemy
