I had to take my intake off last week to take my car to the dealer for a warranty repair. While I had the stock airbox on I realized the significant low end torque/power loss the intake caused. I don't want the stock box on but I want to counter balance the intake's effect because I still love the sound.

What could I get that wouldn't be too cheap, wouldn't be noticed by the Nissan tech's if another repair is needed and wouldn't cause any failure. I'm thinking Y or B pipe. I don't want any droning or too loud but I don't mind if it makes a subtle difference in sound.

Headers and catback are out of the question because they are too expensive and extensive.

Oh and I have no garage so I would need this installed by a muffler shop.

Price range: $150-$250.

 

Y-pipe will give the most gains in your situation, but chances are they will notice it.

 

Ok, how about a b-pipe, will it negate the effects of the intake?

 

I'm nsot too sure not have I seen anything that proves a b-pipe gives subtantial gains, it wont negate it, but probably help it.

 

Put Intake Back On Ive Had Mine On For Two Years And Had Warranty Work Done On It With No Problem Inculding Mass Air Sensor.crank Seal With U/r Pully.i Always Give My Dealer A Great Survey When I Get It,so I Guess They Dont Care About Mods.

 

You just got lucky, b/c I'd say 90% of them will raise the flag if you have mods. My dealership told me to get the bungs for my O2's and they would call it good .even though I have headers.. I may be lucky as well

 

do you guys think, with little or no modification, the stock heatshield that goes over the stock y-pipe could go over an aftermarket y-pipe? I mean the outlet points are pretty much the same right?

 

The stock y has pre cats so it will look weird being that the aftermarket doesn't...

 

im thinking to hide the y-pipe... ya know. stealth look when it comes time for my emissions test

 

I thought that the precats were in the stock exhaust manifolds, so if you ONLY get a y-pipe (not full headers), then your precats are still there.

 

They;re in both the manifolds and y-pipe, that's why the y-pipe gives gains.

 

Wow. How many cats are there? I thought there was one in each exhaust manifold and one right before the b-pipe. You're saying there's also one in the y-pipe?

 

there is one in the front exhaust manifold and then for the rear its in the stock y-pipe. Thats why when cali spec gets a y-pipe, a pre cat is eliminated.

 

02+ Maximas are all cali-spec.

 

3.5Ls do not have a precat in the stock Ypipe, only on the manifolds they do.

 

Ok, so would a b-pipe be worth it?

 

I knew it! I thought I was going crazy.

 

im looking to do exhaust and intake as well....im going w/ the y-pipe most likely

 

Mine did ... The y-pipe has one after coming out of the ex manifold , and again a little more down right before the main cat, not to mention the units nestled in the manifolds themselves
