Diamond Eye makes a great exhaust kit and at Diesel Power Products we take it a step farther by offering you a choice of various mufflers or straight pipe to go with their systems, as well as several exhaust tip options.

DETAILS OF EACH MUFFLER/ELIMINATOR PIPE OPTION

Diamond Eye Muffler: This is the standard muffler that comes in the kits. Featuring a stainless steel construction and perforated core, you really can't go wrong with this muffler. The muffler itself gives the truck a deep tone, while not being overly loud and does a good job of reducing exhaust drone.

No Muffler / Straight Pipe: For those that want the uninhibited sound of straight pipe, here it is. This is a complete kit, but instead of shipping with a muffler, you will receive an eliminator pipe to give you the exhaust bark you're after. If you ever want to put a muffler back into the system, you'll merely need to remove the eliminator pipe and install a proper length muffler.

EXHAUST TIP OPTION

No, it won't add 20 horsepower or give you better mileage, but adding an exhaust tip (or tips on dual kits) simply adds the finishing touch. As another way to make ordering easier, we allow you to simply add Diamond Eye's most popular tips right from this page to complete your kit. You have the option of Diamond Eye's 4" to 5" angle cut, rolled edge, bolt-on tips in either a stainless steel or black powdercoat finish. We will add the appropriate amount of tips for a single or dual kit. And if you either don't want to add a tip, or would like to choose a different option, no problem, just select "No Tip(s)."

Great Bang for the Buck!
Size: 5.25” Woofer
These R50 Studio Monitors are worth every penny. One could easily spend a heck of a lot more to get less. Have been a pro audio engineer my entire life. These monitors kick out clean, solid bass and accurate highs. Klipsch did a excellent job designing these monitors. Perfect for smail spaces where fidelity is critical. If you wall mount these, make sure you leave at least a 1.5 inch air gap between the back of the monitor and the wall. These units are sweet.

Worth the price
Size: 5.25” Woofer
I had in ceiling front speakers and went with these instead. The front ceilings are now height speakers. Sounds great now.

Great sound. I can turn my stereo up loader than I care to listen to it and notice no distortion.

THE BEST SPEAKERS
Size: Pair, Size: Pair
These speakers are the best sounding bookshelf speakers i ever saw or heard. The sound from them is clear even from a cheap crosley suitcase record player and the bass is just awesome because you can actually hear it and it ties my songs together when i can actually hear the baseline. They work extremely well independent of a separate subwoofer because the bass is very strong! Another point of praise is that the decibel count is very high at 93 which means on very low power they perform loudly. Even on low volume from my Aiyima A07 Premium amplifier, they can be heard throughout my house. They look so cool and appear to be very high quality build and strength. They can be used for whatever you want (provided your amp is compliant) they're super easy to set up because all you do you just attach the sticky rubber feet on the bottoms and the grilles are magnetic for whatever aesthetics youre going for. Definitely worth the money (i bought them on sale for $230) very top notch speakers!

Very good speakers
Size: Pair
The r51ms are used to compliment my klipsch rp500m speakers and a 12 inch subwoofer in a large living room. By placing the r51m speakers to the outside walls , and the rp500m speakers to the interior, closer to the amplifier, and with the subwoofer set on deep bass only at just enough volume to barely compliment the sound, the large living room is more than sufficiently covered with at least true high fi quality sound, if not true budget audiophile sound. My entire 2.1 system is all klipsch. That's how I want it. I am using them with a high powered tube amplifier, so presence and clarity is awesome. Placement is critical. I was initially disappointed until I switched the r51ms to the spread to the outside walls position, and the rp500ms to the interior, closer to the amplifier. The difference was remarkable. The 2 different klipsch speakers, ie one a rp and the other a r series blend together perfectly with no clash whatsoever because of somewhat more refined sound on the rp500m speakers. The rp500m speakers do sound higher end , but they are supposed to, but with the speakers as outer r51m and inner rp500m, and the klipsch subwoofer at deep bass with just a touch of volume the result is sound of such quality that I can honestly say I can be content and satisfied with it. I can say my system is complete, and no further improvement, upgrades are needed. Tower speakers as primaries are not necessary because of the high quality of sound and the high sensitivity of the 4 klipsch bookshelf speakers and klipsch subwoofer. This saves me money during this rapid inflation period of time. I could easily say that what I have sounds more than good enough to be satisfied and content with without any desire to upgrade further at this point. Shipping speed was excellent via Amazon itself, and the box and speakers arrived in handled with care and new condition. I am not disappointed at all now that the r51m speakers are the outside speakers, spread apart from corner wall to wall to compliment the interior placements of my rp500m speakers by klipsch. Im all klipsch here and I love it. 5 stars categorically. As previously stated, I see no need for primary tower speakers, even in a large living room, and that equals high quality sound and savings of money at the same time. I recommend these speakers. They do more than just do sound quality wise.
