PM me if anyone wants to hear the exhaust.
I'd be up for it. I'm close to heartland. Mavis/Dundas;

Currently I am looking add test pipes to the OEM Exhaust. But this thread is making wonder how would it sound with the OEM Exhaust Mod. I guess what I dont know is if the Exhaust Mod is louder than Replacing Primary Cats using Test Pipes.

Question.. Purely based on the sound of the exhaust; what I can conclude from this thread is the following

OEM Loud to Loudest
1. OEM Exhaust
2. OEM Exhaust + Primary Cat Delete
3. OEM Exhaust Mod
4. OEM Exhaust Mod + Primary Cat Delete

Did I get the order right? Is 3 louder than 2?
