High Flow Cat Vs Decat

[simdog]

It's been said by others that driving behind someone with a decat/gutted cat is obvious because your eyes can get watery from those noxious gases

Hmmmmmmm i sound old, cats were manditiory in the UK in the Early 90's, but i dont remember having sore eyes before then or anyone complaining about it. What i do remember is a Rover catching fire because the owner parked in long dry grass and the heat off the cat ignited it.

So decats are safer!!!!haha

The question was answered by the first respondent... going to 2.5in would be inferior to any halfway decent 3in cat.

Get a Venom 100cell metal cat - the biggest you can fit ( I have the 5in one).

My exhaust is 3.5" To me it would make sense to use a 3.5" "CAT" though ive noticved alot of people will just use a 3"

Any input apprecaited

Pipe size changes are bad. You work it out from there.

Your exhaust a 3.5 cat back so 3 inch cat will not be a restriction if it's good quality
