Advice from those that know...

Hi all and thanks for reading.  I have a 2010 Mk2 Octavia VRS 2.0TSI CCZA that I've done a few basic mods, Bluefin Stage1 remap and Raceline induction kit.  The car is running great except for a little chirp from the clutch when I reverse and sometimes in first.  I'm wanting to move forward with some further mods.  I've booked in for a longlife (Stockport) turbo back custom exhaust with sports cat so I was wondering if anybody else had used these guys and how they got on.  Once I've had the exhaust done I've been thinking about some other mods to compliment everything and I've been considering a Sachs performance clutch with SMF.  Has anybody else had one of these fitted and how does the car idle after replacing the DMF.  There is a lot of write ups both positive and negative but I just wanted to gets some experience from somebody with a similar setup.  One thing I've found with the stage 1 and induction kit is that I do struggle to get traction so I was wondering if I may be better investing in some other mods to sort this out before I do anything else major.  Again, thanks for reading.
