2004 Nissan Maxima 3.5L
Engine=109k
Transmissions= 179k
This is my second motor that was installed at 70k miles ago and now on my odometer has 179k miles that make an engine got 109k miles on it now. I have not yet decided to keep a car or not but let say if I do. What options do I have to delete front & rear pre cats? I want to avoid buying new F&R pre cats every 60k miles and damage engine before it get to late. I know some of you will say gutted the cat but to do that it need to be done really good otherwise engine get damage soon. Can't I just unbolt the y-pipe?
Very common on VQ35 and 2.5L engine
