hey im about to order a downpipe with a 200 cell sports cat,  but i wonder  will the cel "check engine light"  appear if i go for a 3" downpipe??

 

is it better to go for the smaller 2,5" downpipe with 200 cell cat?

 

here are the ones im thinking of buying first one is 3" the second one is 2,5"

Hi mate I put a 3" downpipe with sport cat on well over a month ago and no check lights ever came on. Just make sure lambda sensors are connected. Mine is Milltek though

hey there thanks for your answer ,  i  have looked at milltek to but its a bit out of my price range

 

how was it to drive after you put the downpipe with cat on was it a big diffrence ?

 

best regards

You can feel turbo spool quicker but im having problems with my car and am only getting 11psi where it should be 19-20psi. Had it working fully for couple days after changing N75 valve and it was a different car to drive but without full power cant really say what it is like.

okeej man sorry to hear that hope you get it sorted

 

  i just ordered the 3" downpipe with 200 cell cat =)

I also had the miltek 200 cell sport cat with no problems, keep an eye on e-bay i picked mine up for £180.

damn thats a good price for a milltek i've looked and looked on ebay and all the ones i saw were about 6200 sek about 486 gbp they were new though

 

so i bought the 3inch one from germany on ebay  so i hope it fits and that i dont get any issues with the cel "check engine light"

 

but if i do i will map it out
