DNA MOTORING CBE-NTT07-56L Stainless Steel Cat Back Exhaust System [Compatible with 04-15 Nissan Titan]

Getting a stainless exhaust at this price is unheard of. All the pipes are stainless. My magnet would only stick to the muffler and only the outside wrapping on the muffler so the exterior wrap is galvanized steel. The interior is also stainless on the muffler and the Y exit pipe. The pipes after the muffler are also stainless, they are just not polished like the front Y pipe is. The muffler is a single chamber, and you can see all the way through it. The sound is not as deep a rumble as the Flowmaster I had on there before, but honestly the Flowmaster single chamber was getting old listening to it on the highway. It has more of a factory sound but a little louder, and it pops somewhat when you floor it, but I was looking for a quieter system so this is what I wanted. It is factory quiet on the highway at speed. I upgraded the clamps with 3x 2.5in and 2x 3in stainless lap joint band clamps and its solid so far, no leaks. I also purchased a 12" 3in stainless exhaust tip as the exhaust is a little short at the end. My only complaint is the tailpipe is too low to the ground but I will make some adjustments to it soon. Soak the catalytic bolts and nuts in PB blaster for days ahead of changing this out. I was able to extract 3 studs but one did break off and had to be drilled and I had to use a 100% carbide bit to drill it, the stud metal is too hard for even my Makita bits. I had to use very expensive carbide that I get from a machine shop type bit. You will need a very heavy duty impact to get them out. Plan on buying a stud kit also for the cats.

Its a decent set up. The welds are all very nice and all the parts fall into place pretty easy. Its not super loud and doesnt drone. I previously had a single flowmaster 40 and it was annoying so i changed it for this. Much happier with this one especially for the cheap price. It does have afew cons thought. The clamps supplied dont seal well so air escapes. I recommend adding sealant or exhaust tape before putting clamps on. The exit is short about 6” so you need to add a exhaust tip. I couldnt find one at the auto parts stores that went over the tubing but they had some that butted up perfectly to it so i just tig welded them together. You will spend more here getting a tip and possibly paying to have it welded unless you leave it short as is but it doesnt look good. The last thing is that it needs is time to break in. After the first drive with it I regretted getting it because on medium to full throttle it made a nasty clapping sound. Like the tone was getting chopped. After i added a resonated tip it helped but didnt go away. After afew weeks it mellowed out and completely went away. Now it sounds good at all levels. The dampening inside the muffler just needed to burn in abit. Afew months later im glad i got it. It doesnt sound as mean as the flowmaster at WOT but the rest of the tone sounds better and it also get less vibration since its much lighter. Id buy from this brand again i think its super cheap(price) for everything you get and sounds good too

Nice fit, good welds, good sound, but you will definitely need to get an exhaust tip if you want to see it. Would buy again from them in the future. Bought another kit off of eBay that was total junk leaked at every joint. This fixed my issue.

The media could not be loaded. Excellent product for the money hands down. Quality parts and quality welds and tubing. Ignore any negative review on this. Fit correctly and with ease. I mean you will struggle a bit since they are heavier parts and you are on your back under the truck but still saving bank vs. having a shop do this. Remove old one by cutting a few tubes off with sawzal and metal blade. Parts line up great to all hangers. I put a video in with the sound - excellent burley sound. Couldn't be happier.

The media could not be loaded. Perfect fit, no issues whatsoever. Sounds louder than my single flow master did.

The drone up a hill and on the highway will give you a headache. Don't try taking a trip unless you bring ear muffs! It's louder in the truck than it is out!I had to buy a resonator and install it but it didn't fix it. I had to buy a Dynomax Ultra Flo muffler and trash the one that the system came with. So if your trying to save money buy a better kit, it will be cheaper in the long run.Oh, and DNA tech support..... forget it.... All they wanted was a screen shot of my order. Wouldn't help me with the Order number, Part number, vehicle information..... What a joke!!! All they needed to know was the part and my truck but they kept going round and round about a screen shot.

Warning. It is extremely loud inside the cab and outside of the vehicle. I’ve had sports cars and raced for many years. And I tell you, this is obnoxiously loud. I had on a worn out straight through glass pack, which was quieter.

Very pleased after installing and using for a couple months - especially considering the price. Excellent fit up without leaks & constructed well.This exhaust is noticeably louder than the factory exhaust. Only issue I experienced was the tailpipe was a little short, so I had to add a tip.
