There is a rattle under my car when i accelerate at about 2,000rpm. Sometimes it seems like it happens when it shifts gears. Maybe it is my heat shield? It also could be my aftermarket dual exhaust i had installed. If anyone could give me advice on what else it may be ?

its more than likely the aftermarket exhaust. thats where my bet would go.

I had it checked out and everything was tightened. could it be the heat shield? the only thing is, it never rattles when its cold
