Monster® Diesel Duals Exhaust

Very fitting.

This is no cheap, ill-fitting aluminized exhaust. It's a heavy-duty stainless Banks Monster Exhaust system with constant diameter 4" intermediate pipe and two 3½" tailpipes. It fits better than the competition, because Monster Exhaust utilizes the factory hangers and maintains proper clearance to all under-vehicle components. Unlike other split-duals, Monster safely clears the spare tire, shocks and brake lines.

Performance art.

With nearly five decades of engineering airflow improvements, Banks has mastered the art of maximizing flow while minimizing backpressure. The polished straight-through Monster Muffler, mandrel-bent head pipe assembly (non-cat-converter-equipped vehicles only), intermediate pipe(s) and tailpipes improve flow up to 150%, virtually eliminate backpressure, lower exhaust gas temps and deliver more power to the ground. And the 6X5” polished-stainless angle-cut rolled-edge tips have real “show” quality--get 'em in high temp black or chrome-over stainless! And to help keep them looking good, there's 1/2" air gaps to keep heat from tarnishing the finish. Adjustable clamps let you position them on the tailpipe just right.

Not just flow-tested. Sound-tested!

Many straight-through mufflers deliver an obnoxious drone that overpowers conversations. Monster Muffler is extensively sound-tested, and engineered with a unique expansion chamber and high-temperature packing. Instead of a drone, you're treated to a rich exhaust note that's authoritative, yet civil. It sounds as great as it looks!

This system has a "split side duals" exit

LB7 tuner & exhaust: Way More Fun Than Any Muscle Car I’ve Owned...

2005-04-15

I pull a 12,000 pound construction trailer with my GMC 6.6 D/A 2500HD. I have installed the Six-Gun, Speed-Loader, and [Monster] Exhaust. WOW!! I recently towed 2,200 miles from Florida to Indiana and back. Mileage is way up. Exhaust temp is way down and the torque is Unbelievable. Without the trailer and just with a little spool up on the brakes at a red light, this thing will smoke just about any production street car. This is way more fun that any muscle car I have ever owned over the last 35 years. Thanks for your great products.

LB7 tuner & exhaust: Even the Other “Chipped” Diesels Could Not Keep Up!

2005-02-07

I bought my new K2500 Crew Cab because I had just out-grown my old 1/2 ton. My business had expanded so much that my old truck was getting tired. I have always been a GM man and was getting so tired of the "Power choke" and "Wait, I'm Cummins" boys bash the DuraMax. I started to look at diesel "hop-up" products. I went with Banks because you are known for your milestone diesel enhancements with over all concern for safety and dependability. After the install I was shocked with the results that were achieved. I went out to show off my new toys, and found that even the other "chipped" diesels could not keep up! I wear my Banks stickers with pride because all the other guys are spending more money on other companies’ products trying to catch me (us). I wish they would only listen and call BANKS!

LB7 Ram-Air & Monster Exhaust: I was shocked...

2010-08-12

Hi Frank, I just wanted to let you know how very pleased I am with your help and Banks' products. I've been very busy, working long hours but I wanted to hold still long enough to say Thanks. I was a little uneasy about hooking up this equipment on my own but, the way Banks packaged everything was a pleasant surprise. Frank, I was shocked when I finished installation of Ram Air System & Monster Exhaust I thought to myself, This wasn't painful at all! The way the exhaust pins slid into Chevy hangers was a breeze! I'm saving all over again now so I can get some more of Banks' goodies! Best Regards and thanks again. One more note: I was told delivery would be 6 to 10 days. Well, I got my equip delivered to my house in 5!!!!! BANKS IS BEST

LB7 Exhaust Brake, Ram-Air and Monster Exhaust: Noticed some very positive things...

2010-08-12

Hey Frank! I just wanted to give A SHOUT OUT! to my favorite Banks guy, and let you know, that I am very happy with my Banks equipment. I got it installed yesterday and noticed some very positive things, such as more power, cooler temp, great sound, and tremendous performance, from the brake. I also want to recommend Rocky's Tuff Trucks, 345 E. Broadway, Gallitin, Tenn, for his great and professional installation of your equipment. He will make a great installer for your product. Please include him on your list of very qualified companies, that do a great job. I look forward to a long term relationship with both Banks, and Rocky's Tuff Truck. Thanks for both of you guys help.
