    True Beauty!Workmanship exceeds all expectations!Sounds astound!

    Posted by Walt@ Lawrence Motorcycle Shop on Apr 16th 2016

    My customer was screaming into the phone"Toce!Toce!Toce! I hear "Yoshi!Yoshi!Yoshi! his mispronunciation cost us a couple of days. The R1 Full Polish project was done with none of his riding buddies finding out. The rear end was draped so no one could see,even the customer was in for a shock! The whole install was straight forward.The finish on the full polish was excellent. The note from the tips was sharp and deep. I like to listen to the idle. The customer pinned it to the rev-limiter first thing inside the shop. Superior product with a custom capability and a tone to match. Plus a Super Staff to help you with questions.

    Awseome sound . loud even with baffles installed !!!

    Posted by steven on Mar 21st 2016

    got exhaust super quick. placed order on a Wednesday, shipped Thursday and at my door on Saturday morning , installed on bike that same day.

    if you never installed an exhaust or have experience. then would of been challenging for some. only thing i had to do was use little bit of silicone to slide the mid pipes on . little tight . but finagled it .

    left the baffles installed, so my wife wouldn't kick me out of the house, no need to even remove them , loud enough

    Amazing sound, awesome quality. Cant beat

    Posted by Tyler S on Feb 23rd 2016

    Was very pleased when the exhaust showed up in a timely fashion. This shipped same day I ordered with tracking information and updates along every step of the process. took about 4-5 days to ship from CT to CA.

    Installation took about 30-45 min from start to finish and was the most easy exhaust I have ever installed. this may be a product of the motorcycle design, but I was very please with the fit, which was a perfect match. only minor alignments were needed to make it fit perfect.

    Then came the first time firing it up to hear this new exhaust. the smile on my face was priceless. Bike has a whole new attitude and aggressiveness to it. I keep going back and fourth on what I like better, the way this looks on the bike astatically, or the way it sounds shifting through gears. Love this product and am very pleased! Thank you! definitely recommend this exhaust as the hands down best option for my Yamaha R1.

    just get one !!!

    Posted by Brian Harper on Feb 17th 2016

    Unbelievable....from the million questions on the phone with mark to craftsmanship and design to sound and performance this is by far the best of the best. In my opinion nobody else comes close to what you get from Toce performance. I don't ever write reviews and I'm probably terrible at it but this exhaust and the customer service are well worth at least my 5 minutes of typing if nothing else. Will never get another bike if I can't get a Toce exhaust for it. Will have my business for life !! Thanks for everything Mark and Dan and all the others that make this product possible !!!

    Amazing sound

    Posted by Collin on Dec 15th 2015

    Very happy with my new Toce exhaust. Videos do not do justice to what these sound like in person. Nice deep rumble when idling along with an awesome race bike sound in the revs as well. These pipes scream when you get on it. Definitely the best, most unique looking exhaust especially for the price.

    2004 R1.

    Posted by Unknown on Aug 21st 2015

    This exhaust is amazing, by far the best one out there. Easy install on my '04 R1. Sound is incredible. Has a deep rumble at lower RPMs but when you get to the higher RPMs it sounds like a MotoGP bike! I recommend this product to anyone who wants to upgrade their exhaust.

    2006 R1 Toce Exhaust

    Posted by Robert on Apr 14th 2015

    Easy install. Sound is absolutely amazing and definitely exceeded my expectations. Thanks to the Toce Bros. for making such a great product. From the first call I made to order the product, then receiving the exhaust within two days, and then the sound of the new installed exhaust everything worked out smoothly and easily. Would definitely recommend this exhaust to anyone looking, and would definitely purchase again.

    great fit love the sound of it the clips on youtube does no justice for what it really sounds like and looks sick. I got the cat Eliminator to and the only thing is I got to go and have it custom tuned. I will post what I gain when I do.
