Hi, guys i was just wondering how much horsepower and torque will i gain after putting on the injen cold air intake and the magnaflow exhaust?
and i also want to know which intake and exhaust combo would get me the most hp and torque
thank you

 

from what I've seen by searching this forum for hours on end and looking at dyno's when I was making this same decision there aren't huge amounts of HP to really be gained by any of them. Many dyno's show a zero HP gain and then some guys are getting 10-20 HP. Based on this I just went with what I thought looked and sounded great. I'm not sure how much my HP increased but I can say I noticed a significant difference in the powerband because that flat spot around 4500-5000 RPM's is gone and it pulls all the way to the redline now. It's a pretty noticeable difference but I don't know how much HP that translates into.

 

All the research I've done seems to show 4-7 HP Max... nothing more.

Many CAI's result in loss of torque, however.

 

Wont make a whole lot with just a catback. get the whole thing with headers, test pipes, y, and catback. that might get you 20-25 whp with an intake.

 

IMO based on this I would rather go with a pop charger rather than a CAI.

You will maximize your breathing mods by getting your ECU tuned.

 

yesterday i was on the freeway and a PPW pulled up next to me, we started chatting driving side-by-side and then he says "you should get an intake & exhaust (nismo), i have 35-40 hp gains, blah blah"...

 

Guys,

I have a popcharger and Injen exhaust. My butt dyno says about 15 hp (hehe).

i've been looking around the forum and the nissan parts i've notice the best intake is the injen rd cai i see ppl say it has a nice sounds and as for exhaust i think the stillen is nice

 

I have popcharger and the dyno proved 5 hp gains.

 

I say dont spend any money and save up for a f/i just my opinion though

 

not enough to really feel, just sounds like more..

 

I'd rather do $6-8k in N/A mods for high 12's than $15k for F/I.

 

Rear end gear swap will do more for you then just about any other mod to an n/a car.
