MagnaFlow Street Oval Straight-Through Performance Muffler with Tip

-Installed on 2009 Nissan Sentra-Had it installed by a local auto shop-Craftsmanship is top notch-Has angled tip already on it. Fits perfectly in the notch on my back bumper made for the tailpipe portion of the muffler-Improved my MPG?????? YES!!!!All I can say is WOW! I've been wanting to do a cat-back for my car, but since the only company that did make one stopped I settled for a muffler change. When my mechanic took off my OEM muffler, I could not believe how big it was (roughly 18 inches-length X 8 inches-height)!! If you look at the size of the Magnaflow then you will know there is a huge size and weight difference.I was worried about the sound, but watching user videos convinced me that this was the one for me and I was right! They provide a nice low "rumble" when starting the car and a lower but not annoying sound when in idle. I do not notice them when I am on cruise control (I put at least 85 miles daily on my car during the week-mostly highway driving). It is only when I accelerate and decelerate can I hear them. I am EXTREMELY happy with the Magnaflow!!!! They are exactly what I was looking for in a muffler's sound. Always a nice low rumble.I also want to tell you that I have an MPG gauge that was built into the car and I saw an instant GAIN in MPG after installing these mufflers!!!! No where in their description does they say it will improve MPG, but it did to my car! I was roughly getting 28-30 MPG before and after I was getting 30-33 MPG without a change in driving patterns/habits.PART #:14829DESCRIPTION: Inlet/Outlet Size: 2.25in./4in.Body Shape: 5in.x8in.

The only difference with the #14851 is that #14829 has an extra pipe inside to "muffle" the sound, thus being part of the "street series" vs. "race series". Other users say #14851 has a higher pitch rumble they do not tend to like.#14851:The Race Series is designed for the ultimate in high performance and an aggressive racecar sound. It features a true straight-through design for maximum high RPM pulling power and a 2.5" or 3" perforated core to virtually eliminate backpressure and maximize exhaust flow. The Race Series is recommended for the serious racer, turbo, nitrous oxide fuel systems, or wild cam applications.

Magnaflow is the way to go! My exhaust was falling apart and I needed a new muffler as well, so I decided to replace my old setup with this Magnaflow muffler. You really do get what you pay for, though this is rather expensive compared to other brands.First off, build quality is exceptional. The factory welds are very well done and are leak free. The polished finish of the body is super nice to look at, and the chrome tip is a really nice touch. From the photos you can clearly tell that this is the “lipstick on the pig” so to speak.However, don’t think that you’re going to purchase this and not be required to do some fabricating. This muffler is a UNIVERSAL muffler, for vehicles with 2.25” exhaust pipe. It is not manufactured with any specific vehicle in mind, nor is it designed to fit any specific model. I know that for some reason people will still ask in the question section for this item, “will this fit my 2008 Prius, 2011 Forester, 2000 Miata, Grand Caravan, etc,?” Do yourself a favor and figure out what size pipe your exhaust system is running, if it’s a 2.25” pipe, this muffler will work. The inlet pipe is 2.25” inner diameter which means it is made for a 2.25” exhaust pipe to slide into. You will be required to either weld the muffler to the exhaust pipe, or you can cut a slot into the inlet pipe and use a clamp over it to connect to your 2.25” exhaust pipe. As far as mounting goes—you will need to weld an exhaust hanger onto the muffler body in order for this to work. I repeat, you will need to weld a hanger onto the muffler body in order for this to work. This thing weighs enough to the point that you don’t want this hanging off your exhaust pipe without any support, you will seriously damage your exhaust system and possibly your exhaust manifold if you don’t not affix this to your vehicle somehow. Any exhaust shop will be able to do this if your are unable to weld.As far as sound, I believe this mufflers size is geared more towards a 4 cylinder engine, though as stated earlier it will work with any engine as long as the exhaust pipe is 2.25”. In my case, I’m running this muffler on a 3.8 V6 engine. For me, it doesn’t sound much louder if at all than stock which is fine. In the case of a 4 cylinder engine, this will sound a bit more sporty, “tuner” comes to mind.Overall, this is a great muffler that is well built and does exactly what is expected of it. Know what you’re getting yourself into before purchasing this and do not expect it to be plug and play. You will need to have an exhaust shop install this or you will need to do the install and fabrication yourself. This is a universal muffler, made for a 2.25” exhaust system. Save yourself the trouble of asking strangers if this will work in your car, all you need to do is measure the diameter of your exhaust pipe. If your exhaust pipe is 2.25” this will fit. Vehicle model is completely irrelevant! I would totally recommend this to anyone in the market for a new muffler!

First off I just want to mention I have a Honda Accord (2.4l) and it sounds amazing. In terms of fitment, the shop I went to said the installation went very smoothly and from what I can see it fits like a glove. I personally like the sound, it's not loud at low RPMs and not crazy loud at higher RPMs. I also paired this muffler with an AERO Resonator so it might sound slightly different compared to other reviews. For the price of $220 I think it's worth it, the quality is amazing and looks good on the Accord. Planning on buying another one soon and getting a dual exhaust setup, highly recommend!
