Really awesome sound. Doesn’t have bad interior noise like the normal 40. Pleased with throaty sound. Cost $65 to have professionally installed at local shop. Very pleased with purchase.

This product is great. It was delivered early which is always a plus. I put it on my 2001 Toyota Tacoma and it sounds great. Can definitely get some attention if you want it to.

I had a TRD exhaust system that was just not loud enough. I purchased this to replace the TRD muffler to give it some extra rawr. It sounds really good, not too loud but definitely noticeable. I was expecting a bit more than what it produced, hence my 4/5. I've seen some forum posts stating a concern with a drone noise from highway speeds, I have not noticed any. Note that it needed some custom welding by the shop to get it to fit perfectly (cost of install excluding purchase price was $115). Given the chance to go back in time, I would still have bought it. Shipping was really fast too. Ordered on a sunday, got it by Tuesday evening with the free shipping.

Worth the money. A bit heavier than the stock one. Important, if you already installed a header, you won't see much difference unless you remove the catalyst!

Easy installing. Cut the old brackets off and tacked them on to new muffler.

Can't go wrong with a Flowmaster Muffler. Although I didn't install yet, it came in extremely quick (shipping), was very affordable, and can't wait to get this thing into my truck!

Not sure what I was expecting. Love the sound, it's just illegal in my state.

Good sound, well built. I welded this on my 09 G6 with a 2.4L. didnt want to sound like a ricer, so I picked this up. Planning on putting glass packs on the G6 instead, but I'll be putting this on the wife's Buick because it sounds clean. Little heads up though, it's a little louder than what most would welcome.
