smiffy 99 Report post Posted January 21, 2013 I need to check if the cats are fooked on the GTA. As I only have the secondary cats what size (cell) do I need if I went down the sport cat route? Also what make? Also single or twin? Oh and it needs to pass the mot Quote Share this post Link to post Share on other sites
Smaky 73 Report post Posted January 22, 2013 18 cell, twin singles, only problem is it would be bespoke as no-one I can think of makes them for the 156 GTA Quote Share this post Link to post Share on other sites

Smaky 73 Report post Posted January 23, 2013 These are the cats and guys I got them from before, good because you can fit these on as te originals are and they have the Lambda Boss there ready too and I have seen increases of 6 BHP on a 2.5, so for a GTA I would estimate about the same.

What price are they, Was you supposed to put a linky in? Also will they pass a mot? Only have secondary cats. Quote Share this post Link to post Share on other sites
