Oh man, where to start...

Oh man, where to start... I bought an 8th gen Toyota Avalon because I liked the exhaust note I heard on YouTube. After running a straight through style muffler and deleting both resonators I was still not getting much sound out of it at all, so I started searching around for the least restrictive muffler option on the market and stumbled upon these bad boys. Ordering process was straightforward, shipped within a few hours and I had them in 3 days. Got them installed this morning and let me tell you, what a difference.. My platform shares the same motor with the Lotus Elise and now thanks to total flow, I have that same exotic sound pouring out of my daily driver. They are small, look to be extremely well built, have a nice finish to them and a decent weight for their size. I don't think they do much for muffling the sound they might just take a little bite out of the top of it but they certainly allow for the freest flowing muffler option on the market.
