shelly_star Posted April 12, 2016 Share Posted April 12, 2016 Hi fellow starlet owners. I've owned my glanza for 11 years. It currently has a decat in, but as my exhaust needs doing i was wondering whether there will be a major difference if i remove the decat and install back the original cat.....too risky these days right with a decat? my car is running stock by the way.

H_D Posted April 12, 2016 Share Posted April 12, 2016 stick to the decat Quote Link to post Share on other sites
gtturbo94 Posted April 12, 2016 Share Posted April 12, 2016 well power wise keep in the decat but for mot put cat back in.you will notice a bit of power loss when the cat is back in alright Quote Link to post Share on other sites
Patches Posted April 12, 2016 Share Posted April 12, 2016 If the cars stock and you're keeping it that way then I'd use the cat. The standard ECU is mapped for the cat so chances are you might not even get a performance increase without it. This is my opinion of course. I ran without a cat for a while but recently got a universal one welded in. It probably wont make any difference to the power I want to make, saves the legal hassles and the environment... which no-one seems to give a fuck about on here haha Quote Link to post Share on other sites
