Can anybody recommend this upgrade? I have a 965spd se with a stillen intake, y-pipe, and a Dynomax muffler. What kind of extra power could this thing give me?

 

It added 7HP and like 16 TQ. to the wheels.Also I noticed no difference in sound before and after the install.

 

tested seperately? i wonder what improvement you get in a 1/4 mile run.

 

For $195, 7 hp and 16 tq, sounds like it will be my next upgrade. Could you feel the difference?

 

yeah i figured tested would be 3hp-ish for cat.

 

I'm selling mine pretty soon. I have a straight pipe sitting at home.

and I did feel a difference in the way it accelerated before and after the installation. I noticed a gain in the midrange all the way up to redline. From 3,000 RPM on up there was a noticeable difference. Take a look at my dyno charts to see the <A HREF="http://www.geocities.com/jgadlage/dyno.html">gains</A> that I got from this modification.

 

Tony, you havent put that thing on yet, whats up with that. Your gonna luv it!!! Think the RT Cat made it louder, it will be even louder with the test pipe. I reset my check engine light and I've been runnin fine. I got my FPR and will install it this week end

 

2.5 or 3.0. Which will give me the best 0-60 punch?

 

Maybe a 3" exhaust for SC'ed Maximas would be good but I am thinking that would be overkill.

 

If 3 inch piping is overkill then wouldnt a straight pipe be ALOT of overkill

 

didn't feel any difference. but it did make my exhaust louder... removed a lot of drone though.. gain some..lose some

I'm gonna buy the 2.5" one. Anyone know the best place to get them?

 

thats where i got mine..and they are friendly with awesome prices

Yeah $179 ain't bad at all. Do you know what state they're in? About how much did they charge for shipping? I have the Greddy Catback and JetHot Cattman Y-Pipe, do you recommend the 2.5" CAT (that's what everyone else thinks I should get)?

It doesn't work that way. If you run a 2.5 inch exhaust pipe and it suddenly increases to 3 inches the velocity of the gas flow actually decreases as it fills the increased volume.(That part is physics)

Now a Cat is a restriction of sorts so it's felt that you may need the 3 inch Cat on high output motors with SC and the works.

A 2.5 inch cat is adequate for any non SC Max.(IMHO)

A straight piece of 2.5 inch would probably be better than a Cat, however I think the Nissan engineers did a damn good job of designing a high performance powertrain and I think from reading this board for months the real gains are made with a "Y" pipe.
