2 mufflers on i4 = loss of back pressure??
 

does anyone know whether i will lose back pressure or not if i put 2 mufflers on a i4? for instance two Evo

From what I understand, you will lose back pressure at low RPM's. My GReddy SP exhaust is a single exhaust and I can feel a small loss of pressure. It takes a little more to get moving from a stop. From what I've heard, it is not wise to go dual with a four banger. I know there are some members of this forum with duals and their fours. Maybe they can share their opinions.

i have seen ppl with dual zigen fireballs and they told me, they don't feel any loss at all. yeah i know it sounds unbelievible but that's what they said. im asking this question cuz dual look better than single and if i wanna go with dual Evo, it's only 50 bucks more plus the cost of custom Y pipe. but on the other hand, im concerned about lose of back pressure and the extra weigh of the second can. well i will probably just go with single then

i think you're confused. you need to buy the Evo for $500, then add the dual option of $450 on there. so you'll actually spending $950 total. (i'm guessing on these prices.)

you sure? on its site, it says evo for v6, $649; 4 cyl, $599. the extra is just for the can, no pipes

this is from the greddy homepage ...

from my knowledge, you have to get the single pipe, then add on the dual option. i could be wrong though, but i'm pretty sure about this.

fawk...sorry i didnt see it clearly .i will say no thanx to dual setup then

no, your right Eklypse39. If you were going to buy the exhaust, I dont think you would buy retail. You can usually find it cheaper.(i've seen it for like 30% cheaper on GBC) I have the Greddy MX w/V6 Dual Option on my ride. Email me for a pic steveng

Dual exhaust on 4 bangers that weren't designed from factory that way is something to laugh about.

Haha, yeah. But anywayz, you CAN go dual, but I think the Y piping will need to be like 1.25-to-1.5? I dunno, I don't think it's worth it go to dual unless you got something else to back it up.
