I wana get some opinions before I do this in the summer.
Pros and Cons of putting a dual exhaust on the 2.2

 

I wouldn't, but its your car, do what you like man.

 

Pros - None

Cons - Eliminates back pressure so you actually LOSE horsepower - You'll like like a dummy for a putting a dual exhaust on a 4cyl car.

 

well i wouldnt buy a dual exhaust
jsut get a shop to build me an exhaust with 2.5 inch piping all the way back to the mufflers

 

on a 2.2? nah. on an SS, better. IMO. you dont have the bumper for it to look right. If you got a new rear bumper that had duals or something itll be better

 

i think it would look pretty sick

maybe get a shop to put the piping all the way back then split it with a y pipe like the neon srt does

 

its a 2.2 dude. it doesnt have much power to lose LMAO i kid i kid

 

hey im just workin with what i got lol

Thats done nicely.

I dont know how 2 huge exhausts would look though.


Plus, it does lose some hp I think, so is that important to you?

 

not really that important
ill be adding a header and dp along with the dual when i do it

 

Not only does it look wrong, you lose power.
No go.

 

::facepalm::

Back pressure has nothing to do with it.....


Do it if you want, it'll be quieter than a single.

 

It may look good, but you wont gain anythign from it. Like everyone else said, you'll most likely lose horsepower.

 

You won't lose much if any back pressure by going dual. The power difference would be negligible at best. Plenty of 4 cyl cars come with dual exhaust from the factory (Altima, Tiburon etc).

 

those are only duel tips, the exhaust still only comes out the one side.....

 

see, rear lip looks good. if you didnt have that rear lip it would look like *****

 

you can always just do a dummy pipe.

 

you could always put a hood scoop neons and a nice big wing on the back to go with the duals =/

 

both exhaust tips are hooked up so when its cold outside you can see stuff come out both tips

 

someone needs to end this thread lol

 

If you were to do it they only it would look remotely good imo is with the RK Sport rear lip. Again just my opinion.

 

heres an example of why not to do a dual exhaust on a base model bumper

lol i see alot of hate to the duals, lol your choice man... i like it, i have it, but i am not a 2.2..... so try it why not.... these guys are all haters.... dont listen to them....


hp lose is very minor and easily recovered.....

to the guy who said it will quiet the sound down.... omg hahahahahahahaah i guess you never met me..... hahahaha i say i would have one of the loudest cars around.... even louder then 3 inch....
