Make OEM Exhaust Mod a Little Louder?
I've been extremely happy with the 2 perpetrated pipe mod where you cut off two of the four pipes and weld two new pipes in the existing muffler.
There's no drone at all which is what I love, but I'm looking to maybe find something I can add to make it sound louder but with little to no drone. Car is stock so far with only the exhaust mod done to it (as far as I know from the previous owner lol). Thoughts??? Thanks! |

Yeah Periokid's method was used and done at a shop. I was thinking of just having them cut it open again and cover up the other two pipes. But I heard this makes it too raspy. Is that true?

If you're okay with a little drone, definitely go with the ACM mod. I've heard the original mod and the ACM side by side and the ACM is noticeably louder and more agressive. Also the drone is very manageable as long as you watch what gear you're in/rpm you're cruising in.

My buddy did the 2 pipe mod after I did the 4. We put them side by side and you can def tell the difference. But the difference will not be like the 4 pipes to the ACM mod...... So if your expecting a big change, don't look for it out of the 4 pipe mod and should prob do the ACM mod, but if your looking for a slight increase, go with the 4.....

Ahh I see. Thanks a lot for telling me. What's the difference between doing it the ACM way and the regular way? Also is there a tutorial? I searched and can't find it. And I can't have them do it because I live in Florida
