General LSX Automobile Discussion - really dumb exhaust question but need an answer

ok I just got borla for my car, and it has the dual pipes coming out of the muffler to the driver's side. Is there any difference between the system that has two pipes coming out the driver's side of the muffler, and the system with only one pipe?

this is the nonadjutsable system.

the one with dual tips is the 'adjustable' system.

is that for a 98-02, ive never seen that before

what one? appearently they're both listed as for ls1 f bodies

the one from RPMSpeed is an lt1 catback. probably a typo

I would say no it's just a different tip from what I'm understand and I would say it's the adjustable system. I don't think it would be a performance difference but I think that the one with, the one pipe may be louder. But I don't know. Does it look like you have a place on the passenger side where a pipe and tip can come out?

Well the one i have is the one from rpm speed. I had borla on my old trans am but I cant remember what it looked like. I remember it being a little bit louder tho, but maybe thats just from years of not having the car. The one on rpm speed is listed on other sites as being for an ls1. I had called borla and tried to explain it and he said its for the ls1 but im just confused now
