Is this intake stock? or which parts look after market? I'm sorry I'm a noob.
I have a 2003 c5. If it isn't stock, whats the name of the parts I have?

mvvette97

intake is stock, only thing I see that's not is the smooth coupler and an aftermarket air filter

big red vette

looks like vortex rammer after market air bridge and smooth air coupler

Ayankees2772

what does that add hp/tq wise?

Todd157k

Really depends on the rest of the system. Is there an aftermarket exhaust? engine mods?
If nothing else was done... 5-10 hp. If there's a good exhaust.. 10-20hp

Ayankees2772

I have the magnaflow exhaust.


And this another noob question. I'm not sure if my magnaflow has the xpipe or not. How can I tell?

Xavier Blade

The only way to tell if you have an Xpipe is to look under your car at the pipes. Looking at the back only identifies the cat-back system which yields minimal if any gains.

Todd157k

Here.. stole this from another thread. Its a nice pic of a X pipe. A stock pipe looks like an "H" in that same area. BTW, please go back to the dealer and SHOOT the dumb sob who put the dealer tag on your car.

mvvette97

My Xpipe has like a chamber unlike the one in the picture. Maybe mine isn't really an Xpipe..

Those items plus the red cover over the battery.

That's not a stock air intake guys, it's a Vortex box with a BPP bridge, I have that same setup

Ayankees2772

How much hp is added? I also have the magnaflow exhaust.

verano29

Vortex claims 22hp increase and that is without the ram-air affect. I think they claim a .3 second increase in the quarter mile. I also have one, and I like it.

I would say the gain is about 10-13 Rear Wheel Horsepower or about 13-15 at the engine.

LoneStarFRC

Both mvvatte97 and myself are referring to the intake manifold, which IS stock GM. You are thinking of the aftermarket air filter, no?

Ayankees2772

Not bad. Is that combined with my exhaust? Or is that 10-13 just from the intake? I read my magnaflow is about the 10-15 as well.

All of those "ratings" are just theory. The only way to know what you have at the rear wheels, is to put the car on a dyno. Never had my car on one, and I'd rather save the few hundred bucks for some fun.Me, I don't really give a crap, as long as I can smoke the tires if I feel like it, and keep up with all the wacos on the NE runs. I do, so it's all good.What else do you need to know, as long as you like the way your car runs, and it's fun? Really, numbers shouldn't matter that much, so don't get all caught up in that, unless you're that picky.There are so many mods you can do, but someone else will always have a better dyno run if they have more money to blow on their car.The point is to just drive it and have fun.

Maybe, but you don't add the numbers from manufacturer claims for each mod together. That is known as "ricer math".

My intake manufacturer claimed 15 hp and the exhaust 22 hp. It did not gain 37 hp... and I suspect it is actually closer to 10 rwhp with both of them combined... if that IMO
