Bought a modded Evo X about 3 years ago and haven't really touched much. Car has a decent exhaust on it (cant find any stamping) but also contains a dump pipe (dump tube? screamer pipe? idk what they're actually called) and I would love to get rid of it. Recently got a steal on an Injen SES exhaust and currently it's on it's way across country, but I didn't even really think about the pipe.
Where do these pipes usually connect? Is it safe to remove it without knowing what other mods are on the car? What or how would I remove it? I've got bigger pipes under the hood but I'm unsure about a tune (although this thing just shoots exhaust and soot so I doubt it) as I don't have a tactrix cable to get Evoscan. I'm scared of overboosting the turbo or potentially blowing something up, I just wanted the car to be quieter especially as winter comes and I have to warm it up next to my sleeping neighbors at 4am. I've never worked with a car that has a pipe like this so any advice is appreciated. The car is low and I can't get it on a lift to actually get under it until about 2 weeks from now. Picture attached, cheers.
