It's like driving a totally different car. She just pulls and pulls like she just wants to run faster and harder. Not only do her looks turn heads but now the sound of my max coming down the road has people looking before I get there...hahahahaha.....

I love my MAX now more than ever !!!! Thanks Cattman.

Check out my website for updated pics.

Time fore a dyno or track times. Is your max an auto or 6mt?

 

any fitment issues?

 

Good stuff man. Yeah, if you take it to the dyno or track, post your times.

The Headers and Catback fit like a glove, but it took some adjusting as it was tighten up. I need to find a place to get a dyno and I'm going to be taking it out to Lebanon Valley Raceway on one of the nights that it's open to the public.

 

I got the y, but would love to have these headers. I wonder actually how much more power they produce over what I already have.

 

I wish I could tell you the difference. My mechanic who is a certified Nissan master mechanic told me the headers add a good amount of power, but the most important thing is to have an exhaust system that was made to work together from end to end, which is one major reason I went with Cattman.

Just the weight difference between the stock manifold and exhaust, plus the difference in weight with the UDP has to add significantly to the performance.

Is the combo loud? I've done my whole setup and it's actually really quiet

 

It's pretty loud. Not as loud as the Hotshots or Stillen. You caqn hear me coming a good distance away.

If you want loud get a high flow Cat. I'll try to find a away to post some sound clips.

i got my headers the other day and tryed doing it my self no prob for the front but the back is to rusted on to break free well i took it to a shope and they said the new headers are aggainst the law cause it eliminats the 2 cats under the header well does this effect the back pressure and can i still pass a inspection with the new headers thanx

 

The 5th gen's have 4 O2 sensors, 2 before the cat and 2 after. The 2 behind the cat require that you drill two holes in the pipe and weld in two O2 bungs which also requires that you make up two wire combinations for both rear O2 sensors. se the picture on the website.

Even after doing that I am still throwing the SES light. Tonight I am going to have the dual O2 sensor simulator installed to prevent that from happening.

There is nothing that eliminates the cat and there is no reason for you to not pass an inspection unless it for excessive noise.

If you want even better flow and performance try a high flow cat...but be aware, the noise will increase significantly.
