I recently did a muffler and resonator delete but it will only pop and bang/burble on a cold start, it is only louder when driving and revving later on after a cold start. I want it to pop and bang/burble while driving and just in general revving after a cold start. Why does it do this? I thought maybe the deletes weren’t enough and I possibly have to get a down-pipe + tune. Is it just my car? 😅
