Good product at a fair price.

To match my already installed Magnaflow catback and replace my 20 years old catalytic converters it was just perfect! Installation is easy and fitment is really good. Sounds amazing also!

I was having some issues related to the catalytic converters on my Yukon (P0420 code, only) at nearly 200K miles and 17 years of service. After checking the computer diagnostics, my mechanic recommended the magnaflow gear. I bought the Magnaflow 23453 GMC 5.7L Catalytic Converters in tandem with the Magnaflow 15701 GMC Yukon Performance Exhaust System ( Dual Inlet Muffler Version). I placed my order after chatting directly with the representative (forgot the gentleman's name), who assured me of the deeper, smooth sound with no highway drone. I have moderate skills and some specialty tools, and was able to abate the old system (after a good soak with PB blaster) using my impact gun and a sawzall in two spots. the install was direct and i found that each piece of the system bolted up just as it should. I have been running the system for three days now and am pleased as much by the corrected instrument warning light as i am with the fantastic sound. the exhaust is deeper upon startup and rumbles with a mellow tone at idle. when coasting, the system is inaudible, and under load the deep rumble changes into a more aggressive tone but not too heavy on the ear. this is exactly the type of system i was researching. I am also pleased with the advice provided by the representative at HottExhaust, who described the system exactly as it is. Finally, i was happy that the parts were packed and shipped well; they arrived without damage or trouble.

I am very pleased with the part that I ordered. It came in ahead of schedule and appears to be of first rate quality. I was concerned as to how it would fit but it went together perfectly. I was also very happy with the price as it was about half of what it would have cost me at a local parts dealer. I would not hesitate to order from magnaflow again and will recommend the company to all of my friends.

great product , great price...I can feel my 350 breathe better! more power and it actually gave me 1 mpg
