    Amazing seller, my second time purchasing from them, always the best prices and even throws good offers your way. Description and communication always on point and expect your item to be shipped lightning fast soon after you place the order. Amazing service highly recommended.

    Well they were very responsive for my questions. After receiving the product i had a question and they responded within a couple hours yes not days which is almost unheard of these days. Shipped as they said it would very fast i was impressed alot of sales these days say it will arrive by a certain day and it doesn't. The packaging was also first class, i was also impressed on that, box wasn't damaged either. They were spot on!

    AWE EXHAUST came well package. Quality product. The seller has it listed at the average price as most sellers of this product. They have a place in the listing that saids to (MAKE OFFER). Forget it!, they ignore all offers that ebay was listed for you. I had to pay their full price. There was a Coupon that e-bay had to save $75.00. I used it.

  • Stainless muffler

    I wanted a second muffler on my home generator. I wanted it stainless steel and quiet. This one is well built and really cuts down the sound. Very fast service and it was just as advertised.

  • Straight pipe

    Went from straight pipe that was too loud and obnoxious to adding this muffler and it put the sound right where i like it. No droning at highway speeds. Quiet enough that i can hear my engine but still loud enough to hear the performance of the truck. can't compare to stock muffler though didn't have it when i swapped

  • Worked well

    It performed well at decreasing the drone from my truck while still sounding good.

    It’s not any quieter than the muffler that came with the race profile kit, it just may slightly stifle the burbling sound when letting off the throttle.
