Just received the borla pro xs xl, feels very well built and once added to my TRD exhaust (2007 Tundra 5.7L) I’ll updated the reveiw. But I wanted to show the inside of the muffler cause it’s hard to find good info on these. So in the photo it’s tough to tell but it has a built in x-pipe to even or stead the pulse of the exhaust, most people will call backpreasure which is 1/2 right and 1/2 wrong. Not really a issue with my case (supercharged) but I like the idea that it may quiet things down cause my Trd exhaust is 2.75” at the end.
Revised* sounds amazing, even flow from both sides, definitely sounds great at low speed (rumbles) and at high speed u still know ur in a v-8 but no drone.

Borla quality control sucks! 1 star for the finish of this muffler. The first muffler came delivered with plenty of scratches all over the muffler, both sides! I wasn''t content considering I''m paying for something new and it should look new! Yes I know it will be located underneath my truck but for god sakes check your products before sending them out!!! Photo attached, the muffler that looks the most beat up. Finally received the second unit and this unit wasn''t as badly scratched up so I kept it. I did however polish the shit out of this thing with Metal Polish from Chemical Guys and a micro fiber rag. After the cleaning, I went ahead and sealed it with Chemical Guys Hybrid Sealant. I sprayed 2-3 times a day for a couple days to make sure the finish would last me as long as possible in Chicago''s bipolar ass weather! The same process was applied to the chrome resonatored tips!
This muffler was exactly what my Dodge Durango RT needed! I''ve had it on for over 2 weeks now and the sound is great! As others have stated, it''s a level up compared to stock but not overly aggressive. On cold starts and when you open up the throttle, you know it''s there but cruising on the highway you can barely tell. Very minimal drone. I''m sure if I under coat the body, whatever drone is there will diminish.
I had a shop install a pair of Flowmaster Super 10''s on my truck and the drone became unbelievably annoying! The drone was so bad, people on the 3rd row couldn''t join, let alone hear the conversation from up front!!! So after countless time researching another muffler I finally decided on this Dual in, Dual out Turbo XL muffler. Keep in mind the muffler will come as a Pro XS muffler, but it''s the same item.
As far as a setup goes...I have new 2.5" pipe all the way from just passed the cats to the tail pipes. First it''s the Borla Muffler where the resonator suit case was, then immediately an X-pipe, then out the back to a pair of Different Trends 14.5" resonator chrome exhaust pipes.
The muffler comes in a stainless steel finish with a free flow design. A notch is located inside in the middle about the size of a silver dollar. This hole was described as a way to even out the flow and sound according to the muffler shop. I wouldn''t compare it entirely to an X-pipe which is why I decided to keep mine. I would have located the Xpipe before the muffler but space was limited. Maybe another shop can???
Over all it was a good buy and if I would have known, I would''ve installed this setup the first time and not the third time and almost $1000 later smdh!!! There''s also an option off installing 2 separate units in the rear as well.

I have to say I am a Borla fan now. I have always been a Flowmaster fan since I did my first exhaust. I recently installed a FLowmaster catback system on my 2014 Tundra and love the sound but the drone was killing me with the 5.7L engine and long tube headers. Install this Borla muffler to tame the drone and quite it down a bit and exactly what I got. I love the way it sounds and no drones. Quite in cab but can hear the rumble. People can tell you have custom exhaust but not obnoxious. Don''t get me wrong Flowmaster is a great company but this time Borla has won.

This borla muffler was installed in a 2014 Tundra4.6L doble cab. I went to my muffler shop and they installed for me, they run 2.5" tubes from the cat to the end, 2 in, 2 out, Sound is pretty deep with full throttle, at idle you can''t notice any noise, between first and second gear you can notice a little drone inside the cab but when you hit 45mph and up you dont feel the drone, I only hit 60mph in a city and the sound is pretty nice, I have to hit the expressway to see what happens at hight speed, I feel very good for now with this setup, I paid $250 for installation, I think is a pretty good price

Well I''ve had three different mufflers on my 2007 Dodge Charger with the v6 3.5 engine. First I had the magnaflow muffler which was basically a x pipe inside a muffler case and had some drone. Didn''t like the sound. Went on to a flow master muffler which is has chambers to produce a decent growl and It sounded wrong for my v6. I then cracked that muffler going over a huge dip so I went to straight dual pipes. Man it sounded LOUD but sounded like a four cylinder import car in high rpms.

Fast forward to this week after buying this affordable dual in dual out muffler from Borla. The quality is amazing for this product. Great case welds and has great internals. It technically isn''t a x pipe design but there is a decent opening between the two chambers to allow for back pressure to even out when you release the throttle. No popping noise and this sound is close to a high end tuned euro v6 with a low growl. It is the most quiet out of every brand that I''ve owned but in my opinion the best sounding. It enhances your cars true sound and roots.

Don''t try to buy a muffler to make your v6 sound like a v8. It''s never going to happen. Buy this Borla muffler and prepare for a smooth growl that won''t give you and cabin drone or discomfort at any rpm.

Update: I have received the new muffler and had it installed. Sounds fantastic on my 2005 bmw E46 330i. Would be a five star review if I didn’t have to delay the install due to the aforementioned reasons

Excellent option if you want to bypass buying a full borla cat back kit for upwards of a 1k. Took this to my local muffler shop & had a true dual exhaust set up, (not the phony “dual exhaust exit” like 99% of all cat back kits are anyways) and had brand new piping & exhaust tips installed for 500 after it was all said & done (including the cost of this muffler).
Way better option IMO. Why pay a grand or more for an exhaust that only gives you the appearance of a dual exhaust when you can have the same exact sound if not better for half the cost, with better performance & flow!
I will admit there is some drone right between 1800 & 2k rpm but it has a very nice deep tone & growl but is not a neighbor hater over the top type. Nice growl with a cold start but very low & deep rumbles at idle. Plenty loud & aggressive without being annoying.

Purchased this strictly because I wanted a crisp clean throaty exhaust note. After having Catless with flowmaster super 10 single in dual out for the past 8 years on my 04 silverado 5.3 I decided to install long tube headers and wanted to pair it with a reputable company known for performance. After installing it i noticed a huge difference in sound, my truck became quiet compared to the flowmaster and I was a little bummed at first but as soon as you punch it, the sound is unmatched i began to feel much better about my purchase. Having my previous set up was nice for awhile but it gets old waking up the neighbors and the drone on the freeway would pound my head at times. It will take some time to get used to but I love how clean and musclely the note is when you get on it, the flowmaster had a raddelly sound, was too raspy and sounded like I just wanted to be loud. With the borla I get performance,better gas mileage and a great sound. My only issue is i wish it was slightly louder almost as if you have a good sound system and just need to turn it up a bit.
