Altima Coupe 2.5 Header Installation Write Up...

Nice!

If the cel gets too annoying you can always get your ecu flashed to get rid of some of those pesky codes

Hmm no surprise there. My Sentra threw the CEL around 20-30 miles of driving as well. I let it be for over year until I replaced the stock header back again.

Anyway, speaking of making 200 bhp, doesn't the new Sentra SER Spec V have 200 hp from the factory? Has anyone found out why and what's the reason our Coupe's get the 2.5 stuck with 175hp stock? Is it the exhaust setup, or tuning on the ECU, etc? Considering it's 150+ lbs heavier, it would make sense that if you're gonna pay more for the Coupe, you should at least get the full 200 hp. (+ maybe whatever bolt ones would give after that) to make up for the extra fat.

I noticed some of the Nissan dealers do not have the Sentra with the QR25s anymore (all you get is the stupid "SR" which just has the SER appearance package), could that be a clue that the '10 Coupe 2.5 will get 200 hp??

That would be saaweet!

Thank you kyle and everybody!!!

UPDATE!!!!!!!!!!!

SEL thrown at 25 miles, oh well. I spoke with my pops and we are gonna try the second part of the installation this Saturday.

As for videos. I thought my gf camera was the hot stuff, but umm it stinks, and she isnt that good at recording

Ill try and figure something out but for now this may give you a little taste. (best video of 4)

Hey when you finish up this weekend...send some measurements to Kyle where the flange is gonna mount and follow the directions carefully.Also I'm gonna wait before I install mine just to make sure I don't throw up a light at all. I really don't wan't to risk any issues right now.

Yes CoupeVQ - it did throw a SEL but it wasnt supposed to, i skipped a part of the installation. It shouldnt have done that. The fix is around the corner.

For starters the Sentra is a god ugly car, keep those 200 hp yuck.

Throck aka lenard spelled out the difference on another thread. Something about the rev limit and the torque curve. He went into much more detail.
