Hello Guys,
I really need help on what is going on with my car and if it has happened to any of you guys before. I am at 16k miles and the only engine mod I have is Tsudo Catback Exhaust. Since I got the exhaust I noticed a little knocking sound but it would happen very rarely. Since I got a leak I had on the exhaust I've been hearing this knocking sound almost every time I stop at a red light. The sound comes from the front of the car but almost like is right where the s pipe meets the mid pipe. I don't hear it outside of the car only inside and sometimes It's louder than others but It's not constant it comes and goes when the A/C kicks in and the revs get higher that is usually when I hear it. Sorry for the long write up I just want to give as many details as possible.

Someone please help me!

Have you gotten under the car to inspect anything? It would be wise to get under the car while it is idling and find the noise from underneath. Use ramps.

More than likely, loose bolts on the pipe or not installed in all the hangers correctly.
