got a my00 classic already have a de cat down pipe am looking to get a new centre section removing resonator and cat but been told that if i do this the car will go into limp mode any help guys ???????true or not true

 

Ive run my 98 uk turbo with full decat for a year now with no remap etc and its run fine (touch wood!).

 

hi is this cody from bradford?

 

i no other years is ok but been told that 00 sumtimes have problems with goin into limb mode

 

sory what do u mean by limb mode?

thanks

 

safe mode no/or very low boost

 

oh ok thanks. i dont think that is true i have had an 3" turbo back system with no cats and a 3.5" open mouth DP for a year and it runs even better. if u wer to get it mapped then you would gain the full benefit out of the system.

 

wat car do you have

 

bttt

 

no it wont go in to limp home is the answer its got no reason to

 

Removing the CAT will present no major problem. Sometimes removing the CAT causes the CAT on fire warning light or CEL to come on. I don't think that happens on your model but if it does it is easily fixed with a small electrical device that cost around £10.
Personally I would not remove the snorkle and certainly not if you are not remapping. I have found that while removing the snorkle on its own makes more noise it also reduces power, probably because the air flow is disrupted.
It may be that removing the snorkle, taking steps to smooth the air flow and remapping lead to a slight gain but I have not actually experimented that far after the initial surprise and disappointment.

 

As above no issues with cel on that MY, only later models will have this issue and it will only show a cel and nothing else

 

had some truble with my00 uk turbo when just taking center de cat off and k&n pannel filtter boost went from normal to going to 18 psi and back down to12 psi up and down on throttle in 5th gear very annoying so put a dawes on (tempary) to settle it to 14.4
