So I install a Manzo catback exhaust on my 14 gsr. I barely had maybe like 300 miles on it. What I noticed is that the driver side is black like smog from the inside but the passenger is barely anything at all. When it’s on idle, i put my hand behind and i feel more pressure on the driver side then pasenger side. Is this normal? I heard it is because turbo cars work like this or something.
The EVO is actually fundamentally a single exit, that is then split to two primarily for cosmetic reasons. You can get a single exit exhaust for this reason. If you're running with a lot of black smoke, you may have some parts on the car you are unaware of so would need a tune for those parts potentially. You're in Texas, so Kozmic Motorsports is a FANTASTIC EVO shop to hit up if you wanted someone to look it over, they are in Houston.
Yeah there is only 1 midpipe. The muffler just has two tips coming off. Under low load the exhaust will find the path of least resistance. Under high load/boost it will likely make use of both exits. But really it could be a single exit car, the two tips are just for show. (Two tips are twice as good as one, four are event better)
I had someone at an exhaust shop told me that the reason this happens is because the majority of exhaust gases are exiting one side at whatever point the exhaust becomes two pieces. Likely, the there is no proper Y split. Manzo, as far as I know, is a fairly cheap exhaust and I'd say they don't spend too much time on researching for a proper dual exit exhaust with similar flow to both tips.
