ScoobySTI Posted January 2, 2014 Posted January 2, 2014 Hi guys , a quick one for you, do you need a remap if you swap your standard downpipe for a sports cat, now I know a de-cat would require a map to sort out the glueing and spooling issues but is a sports cat as bad. I have a version 4 STI. Cheers
Jay762 Posted January 2, 2014 Posted January 2, 2014 is it being used with a full sports system or a sport cat with standard system?
scottishtaffy Posted January 2, 2014 Posted January 2, 2014 pretty sure you wont need a re map for that. tho someone may know better lol
ScoobySTI Posted January 2, 2014 Author Posted January 2, 2014 It is not a standard exhaust, it is SS all the way to the down pip, with the un silenced mid section , sounds phenomenal but my standard downpipe has cracked and won't pass the MOT end of the month, don't want a decat and can't find a second hand original down pipe. Thank you.
ScoobySTI Posted January 2, 2014 Author Posted January 2, 2014 Nice one guys, the more info I can get on this the better, would rather a original but a cheap sports cat has come up.
Ash007ks Posted January 3, 2014 Posted January 3, 2014 have a look at the holy grail post mate, I believe its mentioned in there
savage bulldogs Posted January 4, 2014 Posted January 4, 2014 I fitted a sti tmic, cobra bell mouth sports cat and a k&n panel filter to my v3 uk turbo without a remap and had no issues with driveability or mot emissions for 4k miles until I got a esl remap . The classic ecu seems to be lenient enough (or makes minor adjustments to fuelling itself) but I would recommend considering a remap as you'd find quite a substantial increase in power , driveability and maybe even better mpg
