Well, I thought that it was about time that I posted a constructive thread for a change.
Its been 2 years now since I bought my Milltek 2.5 inch catback syatem and its been great to a point. That point being until I had the SC done.
I've had a problem with a slight blow at the catback joint since the conversion was done. The custom downpipe taper flange wasn't quite snug in the Milltek flared tube and the blow was coming from the bottom of the joint. I've been sealing the joint with RTV sealant for about 18 months now but it only lasts for a few weeks before it needs to be taken apart and sealed up again.
I booked the car in at Longlife Exhaust centre, Gloucester, last week for the offending joint to be modified this morning. They have cut out the flanges and fitted a nice sleeved section.
All is well with the world again except for one thing. The Milltek centre box is completely empty!! The wadding that it left the manufacturer with is no more and has been burnt up and blown away due to the intense heat from the exhaust gases.
Longlife are familiar with Milltek and showed me the wadding that's used by Milltek and other companies for NA exhaust fitment. Then they showed me the wadding that is used in forced induction exhaust systems. The 2 types are worlds apart. Obviously they have given me a quote to replace the centre box with something more suited to my car.
So, for those of you thinking of going for big power upgrades through forced induction, remember to upgrade your exhaust so that its fit for purpose.
