I have a borla td and it came on the car when I bought it. I love it but I want it louder.

I have searched and cant find enough on youtube to be satisfied so I'll turn to people that may have taken the route I want to.

I have heard taking the 2 resonators out and replacing with straight sounds amazing. I've heard test pipes will up the noise. Ive heard replacing the h pipe with x pipe is great.

I dont know which combo to do or what would be best sounding.
any imput would be greatly appreciated.

 

You could drill some holes in the mufflers.

 

Test pipes

 

just unbolt the cats from the headers mustangs will be jealous

 

I have a Borla as well and love it . Not sure how long have you had it but i noticed that it took about a month for my Borla for the growl to deepen and sound a bit stronger on mine

 

X-pipe will just get rid of the hiss. Won't make it any louder.

Resonated test pipes will make it louder and play down the rasp. I wouldn't remove anything from the system since they all contribute to the Borla sound.

 

I have found a video of a borla that had the resonators replaced and I may take that route because it will be easily reversible and eventually I want test pipes. If I did no resonators and added test pipes I'm assuming it would be redicilous. Do resonated test pipes make it much louder opposed to non res test pipes. I would like to get rid of the cats eventually anyways.

 

I'm running the borla with a magnaflow x and MD art pipes. There is absolutely no rasp and the interior noise is very quiet, yet the exterior sound is amazing. Just a bit louder than stock when putting around and just perfect without being annoying at wot.

You can get rid of the resonators but I'm sure it will be raspy. I say leave it and buy some non-resonated TPs.

 

Replaced the resonators with straight stainless and it is amazing! It increased the volume with a little bit of rasp. Well worth 50 bucks!
