I have a greddy catback system for the 4th Gen Maximas. Will this also fit on a 2001 Ae?

 

Im guessing it'll fit with maybe a little modifications but I what about y-pipes etc for these cars? What other mods can I do to bring out its potential while keeping great reliability being I do alot of driving

 

I am pretty sure that it will fit, I think that it comes out just a tad too short if I am not mistaken.
As for y-pipes it really depends on what you want out of the car. Easiest option would be to purchase a Warpspeed Y. The second option would be to just purchase some headers, albeit a bit more labour intensive than just the Y but worth it.
The VQ30 is almost bulletproof and has proved so time and time again.

Good luck and have fun.

 

Not sure about this kit, but the Cattman 3” was different through the “over the axle alley”. That was where the most significance difference was.

Y’s and such won’t be affect since this bolt to the cat, bur as was stated earlier, length might be.
