joshuaar Posted November 5, 2011 Report Share Posted November 5, 2011 Hey guys, I went to see a guy at power flow earlier about having a de cat pipe on my 1L arosa but he told me that it would cause big problems for my car as it relies on the back pressure from the exhaust, I wanted to know if anyone else with a 1L has fitted a de cat and what problems have you come across? The reason I need a de cat is because of the height of my car it catches cats eyes and bumps in the road. Any help would be appreciated Quote Link to comment Share on other sites More sharing options...
Pete91 Posted November 6, 2011 Report Share Posted November 6, 2011 Does the arosa have a back pressure sensor? Cos that'd be next to the cat so if the cat was removed the sensor would need to be relocated. That might be what he's referring to as being a problem. Also will getting a decat not be a bit of a pain in the hole come mot day?? Quote Link to comment Share on other sites More sharing options...

Chrisbee Posted November 6, 2011 Report Share Posted November 6, 2011 When my back box fell off, i had to drive it to gsmotosport, and i really felt the difference, it just had so much less punch, definatly noticed it. Quote Link to comment Share on other sites More sharing options...

joshuaar Posted November 9, 2011 Author Report Share Posted November 9, 2011 Where did you guys go to have your system raised? Because I went to powerflow the other day and they just told me a de cat would cause problems with fueling and that they reccomended a 4 inch jap cut exhaust (no thank you) Quote Link to comment Share on other sites More sharing options...
JoeA Posted November 9, 2011 Report Share Posted November 9, 2011 I've had the back box replaced with a pipe from the mid, no drop and sounds nice, not chavvy just better Quote Link to comment Share on other sites More sharing options...
