Hey guys, Ive recently bought a 2015 chevy cruze Diesel and wanted to make some exhaust modifications to make the car sound better. I got rid of my resonator, but it barely made Any difference sound wise. Was hoping you guys know why it didn’t make much of a difference like it did with my past cars, and also what you think I should do next to make my cruze sound much louder. Appreciate it!
I’m not sure what you got rid of, the large chamber in the center of the car is where the DEF mixes with the exhaust gasses. Most of the sound reading comes from the diesel particulate filter. Unless you are going to delete and tune the car there isn’t much you can change exhaust wise.
Yes...if that's the case, the car isn't going to be very happy for long...
The exhaust itself has no resonator or muffler. Like @TX CTD said, aside from a delete, and then maybe a custom straight pipe to remove that portion and the SCR, there's not much to change - it's a 2.5" mandrel bent exhaust.
go full delete with proper tune up and reep the performance and fuel improvement while also ditching a good chunk of weight. turbo diesels are not very loud creatures by nature since the turbo muffles a lot of sound and GM really stuffed the engine bay and surrounding areas with sound insulation. with the delete in place i would have a race shop do custom cold air intake, and re do intercooler lines to get rid of squish points. that should really help hearing the turbo spool.
Yeah...that is definitely the SCR...crucial emissions component...not a resonator.
Whoever told you that is a resonator had no idea what they were talking about, though the SCR does muffle the sound quite a bit...which is why the car has no muffler or resonator.
