Catless DP & Interior dB
So here is my question of the day... What is the average interior decibels you guys are getting at highway cruising speeds (60-70mph, AC Off, radio off no conversation) that are running any brand of catless DP, I am looking for some data with catelss DP and stock exhaust preferably. I will take data from aftermarket exhaust as well. Also if anyone wants to help capture this data if you have an iPhone can get a free decibel meter app and I would assume the same on android platform as well.
Thanks! |

What about cat less DP's + Muffler delete? Is that too loud for daily driving use? I'm currently with only a Muffler Delete (stock everything else).

Its going to drone like crazy, but thats largely due to the existing muffler delete. DPs didnt add much volume for me, just made the tone more aggressive and a little more raspy.

Just catless downpipes won't change cruising volume by any noticeable amount at all but it will add a little rasp when WOT |

Honesty I don't notice a difference inside the car with all windows shut. MAYBE at WOT but still not significant.
