PEPSI

Hello I'm back with a not so good sounding car, I just uploaded a YouTube video about this problem down below.

I messed up and true dualed my exhaust, straight pipe nothing in its way... What sucks about all of this is a guy I thought I could trust said it would sound pretty good. I just want to know if going from 2.5 in exhaust to 3 in exhaust with an x-pipe would help with this? I understand that with the stock exhaust setup minus the resonators and mufflers sounded relatively nicer than this. I'm trying to go a route that makes it sound like a MK4 Supra. I don't have a turbo yet but I do have a standalone, it's a start to the whole process. I want to know how someone fixed this terrible noise. 🤣💀 To some degree I don't even want to drive the car
​​​​​ with it sounding like this. Sounds like a fart Canon 24/7 no matter what RPM. On the highway it sounds like a very angry hornet flying fast. However I'm still going to keep this car hence why I'm asking on here.

Please help!

The true dual setup seems to be hurting it, lol. I would recommend that X-pipe and probably some resonator to start with. I don't know a lot about exhausts, but I do know that sometimes having a true dual on an inline-six like this one can make it sound like two three-cylinders having a bar fight. So, making the exhaust pulses overlap somehow - i.e., going single or else an X-pipe - would make the sound smoother.

Fix it by undoing what you did.

Kind of can't when someone else welded and threw away all the other parts that were cut off. I was thinking about going with a 3" exhaust true dual with a long X Pipe to help. My car is the equivalent of a clapped out Chevy and Honda.

Why are you fixated on a "true dual" on an inline six?
