De-cat?

I assume my Autech system would be the same as a GTI, looks the same to me when it was on the ramp.

Do you think a removable de-cat is worth doing? Then I can just swap it over for the MOT etc.

Is it a worth while mod? If so, where can I get one? ;)
 
A decat is a decent inexpensive performance mod to do.

Look on ebay US for Sentra cat resonator - i just bought one £10 with £30 Postage - looks really nice too good sold quality. delivered in a week.

However, i tried to fit mine the other day and those bolts are solid! I'm going to have to get some WD40/penetrating oil and spray on every day. I'm sure others will tell you the same. If/when i get it fitted don't forget to smear copper grease on bolts so its easier to undo for MOT.

will post a pic or 2 when i get some time to fit it. :cool:
 
My Sri passed its MOT with the secondary cat (the one in the mid section) removed. Has done for the last 4 years (fitted by previous owner)

The cat in the manifold does all the hard work? Or so is my understanding. Due to the Lambda sensor taking a reading from there? Cat in center section is a backup to further filter any shite and keep Co2 levels in check. Someone confirm this?
 
i thought the precat was there to protect the main cat on cold start up? what i was told anyway.
