After i did my ARH + HF cats, and an AWE touring kit, the car was WAYYYYY to loud with drone, so i added a magnaflow center X muffler that not only eliminated the drone, but it really deepened the exhaust tone, and I receive TONS of compliments and questions about the tone, anytime im out... the cam also helps 
If you are only wanting better idle volume, but quite WOT volume, consider a set of electric cut-outs before your mufflers. |
So my car has npp which honestly I never use. My current driving setup is sport mode with track mode npp. Someone recommended borla 60608 to add when putting headers. Would that make it where its not crazy loud? Also, do you have a video of your exhaust current setup, insta or youtube?
