Best exhaust clamp that I've ever used. No welding for me.

Awesome clamp. Seals up perfectly. If you're like me and don't have a welder, but still want to modify or repair your exhaust, get these clamps. They're quick, easy, and with the sealant on them, there are no leaks.

You don't often need exhaust hanger pliers, but, when you do, you're glad to have the right tool.  Clunky alternatives (pry bars, screwdrivers, etc.) don't work as well.  This Aven tool worked perfectly for both removal and reinstallation of the exhaust mounts for a hitch installation, saving much time and potential frustration (not to mention damaged fingers/hands).  If you need to do exhaust work, just get it. It's worth it.

I installed this system on a '68 Firebird convertable. The Flowmaster description says "will not fit convertable". It will. There is an "X" brace on the convertable's that you have to remove. You can either leave it off, ( The brace is designed to keep the trans tunnel from crushing in the event of a side impact. It has no effect on the floor pan flexing, as some may suggest. ) or you can buy a modified brace from Pypes exhaust systems. DON'T BOTHER !!! I bought one and it was a joke. It didn't even come close to mounting up. The bolt holes were a mile off, and even if they were in the right place, once bolted up it was so low that it would drag the ground constantly !!! The pipes don't need that much clearance, as there brace was spaced so far from the floor pan there was 2" between the brace and the pipes in some spots. Just a bad, not well designed product.  I did put the "X" brace back on the Firebird I installed this kit on by using longer bolts and 3/8" inside diameter thick wall spacers I cut to the appropriate lengths needed for the brace to mount back up and clear the pipes. ( Longer in the front, shorter in the rear.)
  As far as the quality and fit of this kit, It is excellent !!!! It does install fairly easy if you have mechanical skills, as there is cutting to fit the front pipes. Both for length and width. Other than that it bolts right up and clears everything very well. The tubing is thick walled and aluminized coated, all the hardware needed is supplied. The mufflers are the Super 44 series, are they sound awesome. For some people this system may bit a bit loud. My customer changed the mufflers out to the 50 series after he and his wife drove the car a few times. They loved the sound of the car, but after cruising around for several hours they wanted it a little quieter. Keep in mind that was a convertable.
  I have always loved Flowmasters products and this was no exception. I am using this same kit on my own '68 Camaro SS 350 hardtop.

Using Forney 6011 3/32" rods, I managed to get nice penetration on a sway bar (essentially 3/16" thick wall 1" OD pipe). Most of my issues came from my own inexperience (first weld ever!). I was able to reattach the driver side end, which snapped off after 17 years, with pretty solid welds. We'll see if it holds up to country road driving, but I'm fairly sure if there is a problem it's on my end like I said. I need to get a grinder and some clamps then I'll feel more confident about making more pretty welds. However, for the $75 the welder cost me, $16 for the gloves, and $19 for the rods I think I'm off to a good start. The welder wasn't prime but I got it in a week, just in time for my project which was perfect.

Update: 9/4/14
I haven't had a chance to use the welder since, but the sway bar, which gets a workout every day, is still going strong!

Don't expect to be able to attach this directly to an exhaust manifold outlet. I did and it lasted about 3 hours on one of my 318s. I needed something to make sharp turn in a small amount of space for a new muffler and thought this so-called "high temp" elbow would work. It didn't. A waste of a lot of money. Replaced it with regular 250 degree 3" corrugated marine exhaust hose which is working fine. I am not sure why you would ever want to use this expensive part.

The exhaust system fit perfectly, only complaint is in the description. The exhaust system is NOT stainless steel. Other than that everything in one box, clamps pipe instructions and a good price.

These are the best. Just remember you need the black erw pipe with threading on one end for the clamps to perform at their best. The regular galvanize pipe seems to be too thin for this clamp.

My 2006 Toyota 4Runner 4.7L needed a new radiator and I figured after 190K miles, it would be a good idea to replace the hoses as well.  It's a good idea to replace constant tension clamps when replacing hoses so I picked up a package of these.  Stay away from the old, dinosaur-era screw-type hose clamps that your father used.  These constant tension clamps will expand and shrink along with your hoses and plastic radiator parts to help prevent future leaks.  Plus, I think we've all over-tightened a screw-type hose clamp at one point in our lives--these clamps help prevent that.

These types of clamps clamp very well....if you buy the correct size.  Rotor Clip has a very good web site that describes every detail of these clamps you could possibly need and helps you pick the correct size for your application.  Details can be found at rotorclip.com/cat_pdfs/ctb.pdf

I measured my radiator hose and found the outside diameter to be 1.9 inches (48.3mm) and after checking Rotor Clip's website I found that these CTB-50ST clips would fit my application.
The "50" in the CTB-50ST refers to "50mm" maximum diameter of the clamp when it is fully opened.  I took some pictures of a clamp at it's natural "rest" position (1.625" or 41.2mm) and full open position (2.022" or 51.3mm).  These measured results are pretty close (within one or two millimeters) of what Rotor Clip has on their web site.
The "ST" refers to SAE-1074 spring steel.

These are very good clamps.  Strong, springy, and stiff all at the same time.  No need for a special tool to open them, just grab a large pair of channel lock pliers (if room allows in the engine bay) and you're good to go.

Bottom line, if you've got a hose that has an outside diameter of about 1.7" to 2.0", these should work for you.  There is one review that says these will fit up to 2 3/8".....nope, not gonna happen.  As you can see from my picture, there's no way this clamp is opening that wide.

Very happy with this purchase.  I wish they sold these clamps at my local auto parts store.  When I need clamps in the future, I'll be sure to check Rotor Clip first.  And hey, they're made in the USA!

I love this tool!  I had tried to lower the exhaust on my 2009 Subaru Foretser to install a hitch, but could not get the rubber doughnut exhaust hangers off.  I tried evrerything, but they were on there tight and I couldn't get my hand in and get any leverage on any of them.  I had all 5 off in less than 5 minutes with this tool.  Worth the cost in time savings alone.  I highly recommend this tool if you do any exhaust work.

This is a good deal for an exhaust tip. I welded the tip onto my exhaust, instead of using the provided clamp. Make sure that your vehicle exhaust is already 3in other wise this will not fit the exhaust on your vehicle.
I put this on my 1991 F350 7.3 IDI Diesel

Just to let everyone know, these are lap joint clamps. They clamp a pipe joint that fit inside the other. I ordered these when I must have been brain dead by mistake. I really needed butt joint clamps. All worked out in the end. They are some killer clamps. I used these 8 years ago. The bolts were totally rusted but the clamps never leaked. I used an angle grinder with a cut off wheel to get it off.

I replaced the exhaust on my new Ducati Monster 1200S and in doing so I damaged the T-bolt clamp. To be honest, I think that after the builders at Ducati install the exhaust they crush the t-nut so it can't be removed without destroying the clamp. My suggestion? Buy this one rather than ordering one through your Ducati dealer. This was a few bucks while the once from Ducati was $26. I guess shipping from Italy accounts for some of the overhead but $22 worth? To be honest they aren't identical, this one actually seems beefier. Anyway, order one BEFORE you remove your exhaust cans!

These clamps are great. They're really easy to install and look pretty sleek. The look and feel better than regular exhaust clamps.

They came with some black putty, I'm actually not sure what that was for, so I just took that stuff off and installed it without it.

Finally a great, strong quality hose clamp.  I bought four different sizes for my project truck.  I recently did some work and replaced the hoses and clamps.  I bought clamps from the local parts house.  About 1/3 of those failed when I tightened them up.  Either the screw stripped the clamp itself or the the housing that surrounds the tightening screw failed.  These clamps appear to be very strong and the after the initial use, are very strong.  I am glad I got these to replace the inferior ones that I initially tried.  I will update the review if anything less that expected occurs.

Great stuff - helped me properly seal a poor weld job on my exhaust flex pipe. No more exhaust leak and really easy to apply. No smell and dries quickly.

Crappy if you're a yaker. Biggest clamp they could of made for a fish finder. Guinness world record for dumbest mounting options. I don't know how more I can express how aweful and not thought out this clamp is. Not to mention you can't troll in a kayak with this mounting system lol. What a same. If the clamp won't fit there is a bolting option or screws. Highly unlikely unless your transom is over 3inches. Electronically amazing. Don't use cheap batteries. Also only alkaline batteries or you can't use side finder and light at the same time. Very good at temps. For depths well don't run it unless its 3feet or more. Go under 3feet and it resorts to demo mode. You have to turn it off and on. Would be 5 stars if they could have alternate mounting options not something ghetto I have to rig. The over sized clamp is very limiting. Also if it had a rechargeable option. Like a permanent battery or something.

Extremely well built.  Need to purchase other clamps.
