Exhaust Question...

down4it · 04-08-2008, 04:55 AM

Has anyone tried using Borla Pro XS mufflers on a 335??? I am running catless to dual Borla XR-1's right now and my car is one of the loudest 335's out there... I have catless dp's mated to full 2.5" mendrel bent piping to the dual XR-1's, the rear section (mufflers) is on V-bands... So i am having Royal Muffler take off the XR-1's and put on pro xs mufflers instead since they are deeper and more quiet... I am a bit tired of the noise but the good thing about V-bands is 2 bolts and i can swap between mufflers... The car with cats on with the XR-1's sounds great but with catless it is very loud... I just wanted to see if anyone has heard anything about the Pro XS mufflers...

How about some resonators if you don't want to put a high flow cat in there?

Yea I can tell you putting catless DPs onto a resonated exhaust didn't make it much louder at all.

I tried adding 2 small resonators before the XR-1's and it did barely anything for the sound and just added weight so i removed them. I am going to have the XS mufflers installed tomorrow with some CF tips and hopefully that will be all i need to do to make the car a bit deeper and more quiet... If that doesnt work i'll try adding resonators on the piping again with the new mufflers. Good thing is the v-bands make everything interchangeable and easy...

Down4it was banned... The Borla Pro XS with catless DP's is amazing is all i can say... The XR-1's would be great with catted dp's but are too loud and raspy when catless. The pro XS sounds like a euro car should, not too loud just deep and gets loud at WOT... I would recommend anyone get the pro XS mufflers over magnaflow any day of the week if you are running completely catless. It also has no drone at all... I have now spent enough on my exhaust all together that i could have bought a full titanium one.

At least it sounds perfect now...
