Custom Borla Exhaust
I am puzzled...I wanted to create my own exhaust..I wanted to keep things simple. The plan was to change the mufflers only.
after long search, I decided to get the Borla XR-1.. supposedly a race muffler,i.e. supposedly LOUD one. I got 2 from Ebay, installed and it made the car MORE QUITE!!! honestly, the Borla killed all the raspiness.. now though the car sounds more quite, it has a much more deeper tone-something I really like. so after some thinking, I decided to delete the secondary cats. this was completed recently, the sound is a bit louder however, the 2 issues below are still killing me
I need your advice guys, as this is not making sense to me, usually the higher the revs the higher the flow of gases and the louder the exhaust (am I wrong) |

what will happen to the drone if you remove the fiber glass packing?
already there is a lot of drone!! I have attached the sound analysis. All these were taken at idle Last edited by Rimos; 04-22-2017 at 02:11 PM.. |

hmmm, I am bit confused, does the Borla drone, or is it too quiet?
Removing the packing should make it louder. Do you know how many chambers the Borla has?

I feel your pain. When I got catless DPs, the sound was a little louder and deeper. I wanted it to be louder still, so I replaced the stock exhaust with a full Supersprint exhaust (mid-pipes + axleback). To my disappointment, there was absolutely NO change in sound at all from the stock exhaust. I'm still a bit bitter and feel like I wasted $2k

Thanks for confirming my fears, Before I went with borla, I listened for countless hours to the supersprint and eisenmann. But I always felt that they didnt sound louder than the stock exhaust. The problem, or rather not, is that the ORM muffler is a straight through on both sides. I didn't know that until I cut them. Not only this, but also the right one (the one with the valve) is not even perforated!! With the supersprint, do you also feel that the sound is less at WOT? Does it sound more quite above 4.5k?? |

I like the power of simplicity, really amazing! second, for the sound, it ticks a lot of my boxes except for the raspiness but I am willing to live with that. The MOST IMPORTANT question is does this setup have a lot od drone? literally speaking, I was out in my car yesterday for 40 mins, my ears are still ringing till now |

You can certainly hear the exhaust while cruising, but it doesn't get to the point of droning. I think leaving in the mid-pipe cats helps with this a lot. I think that was the elusive single burble! |
