Thinking about a Borla XR1
Current setup is FM 2.5" downpipe mated to a 3" exhaust with an 18" resonator and an ebay canister.
After listening to some mt exhaust videos, I'm thinking I can get a better quality note out of my exhaust. Idle sounds great, deceleration sounds great, and wot sounds great...but there are a few areas in the exhaust that sound too..."honda-ish" for my liking. I was thinking about pulling the canister and sticking in an XR1 with just a tip on it. It's not that the exhaust is loud, I just wish it was more mellow sounding is some rpms. Any idea if this would be a waste of time or if there are better options? Also, I don't want to shove the largest straight through muffler posible I can in there...been there and done that, it sounded like ass. |

this is the muffler I'm installing on June 5th. |

I'll probably be getting one of these:

At the end of the day, a perf-tube muffler is a perf-tube muffler, the character of the exhaust isn't going to change all that much. If you are having resonance problems at certain RPMs, I would experiment with adding in an additional resonator to smooth it out before you run out and blow a bunch of cash on another muffler.
Does anyone have a sound clip of before and after adding a resonator before the muffler? |

I added one, it barely made a difference. cut out some drone.
the key to win is what I posted. I mean, look how well it works: |

i've had mine with basically open downpipe that exits just behind where i sit, and after three months of dd its getting a little annoying and ill be putting on a muffler soon. Because im A) scared that i will get pulled over because of the loudness which will lead to them looking under my hood and having to take everything off, and B) its pretty loud

I currently having a 4x9x14 muffler, 4x12" resonator, and 3" metal core cat, and it's perfectly loud for a race car.

the key to win is what I posted. I mean, look how well it works: I'm sure the big ZOMFG muffler that you'll be running will be very mellow at cruise and even at WOT, but I bet if you ran it sans resonator/cat you would still get that farting BLAT sound in the midrange. |
I'm not sure if I have room for another resonator unless I redid the whole exhaust. It current has a fake cat right underneath where the seats are and an 18" resonator right before the trunk. I might be able to squeeze another small resonator underneath the trunk area...just depends.
It doesn't "rasp" like a honda does...it just sometimes has that plain, jane drone sound to it...rather than having any character to it...if that makes sense. |
1:00, that's the noise I cannot stand, it's LOUD when the wastegate opens. the dreaded honda WWWWWWWWHHHHHHHHHHHHAAAAAAAAAAAAAAAAAAAAAAA |

Borla's are quieter than Magnaflows, but not as robust. It shouldn't be an issue on your car.
