hey guys i have a new question. i am just got a new exhust and now when i running through the gears when i shift into the next gear i hear this puff or back fire thing i am not sure i have no idea what this is. my engine is running great i am not sure what it is but it always does it above 6200 and sometimes 5500 let me know what u guys think

It's probably just the sound of the exhaust.

I'm guessing the sound also, but it could be a leak in one of the connections. Get it on a lift and listen under the car for a leak.
