i always notice a loud rumble for few seconds when you start the 135 cold but goes away after few seconds is there any way of keeping that noise through out?

Are you talking about the golf tee mod? There is a flap that's open in the exhaust when u start it so it louder me then closes and quiets down.

Do the golf tee mod. There's a vacuum line under the bumper near the exhaust and you can either zip tie it or use some plugs. Look it up in the DIY section.

The engine is in cold start mode. That's why the exhaust tone is different during start up
