I order 2 of them, I figured it'd be worth a shot. It they work out, I'll l et yall know.

has anyone tried these?

 

I just got the "lap" joint kind in the mail from Summit Racing today.




Seem like good quality, we will see how they work

 

I assume these eliminate the use of silicone couplers or do these go on top of the couplers to make a tighter seal? Either way good find

 

looks like they are for the exhuast.

 

O yea for turbo piping.

 

Doesn't look like they would seal very well. If you want good sealing w/o using leaky arsed flanges, use either ball joint flanges or v-band clamp systems. But let me know if these work out.

 

Yhea, I was not real thrilled when I found out my piping just used clamps but I did read a few things that said clamps work just fine. I was going to just use a regular U-shaped clamp but I thought these looked a little bit better.

 

I could not find ball joints that were 2.5 in and 2.5 out ... and the guy at summit SWORE by them

We will see. I am even going to attempt it for the header to see if it can stand the that. I have to call dynomax monday to get a temp range on them


Mike- Same thing..Let me know how yours work.. I will be fitting them in the next week or so and then testing them in 3-4 weeks.. depending on my pipes

 

I had that style on my pfi kit..... the reason i ended up welding the two pipes together was that the clamp could never get tight enough. The pipe fell off while i was driving - 3 freaking times.

 

I hope I can find one of these cheap knock offs at the auto parts store tomorrow. I have to be able to remove my muffler easily at the track. And right now, I have a cheap coupler with the U shaped heavy duty clamps. Since it crimps my piping, it's dang near impossible to remove without cutting the coupler.

 

That sucks.. I hope these are beter

 

But jointed or lap jointed?

 

basically a lap joint - minus the ridge inside that is seperates the two differently sized portions of the clamp.

 

Sorry....clarify for me. The pipes that you were trying to connect, did the over lap on top of each other or just but together?

 

This strap coupler connects two equal sized pipes butted together. I just call Summit and ordered one of these while I was buying something else. I told him to throw a 2 1/4" coupler in and asked him if he's had any experience with these. He said, yes they do seal and they are great for butting two equal sized pipes together. He even said he tried to repair his flex section on his Honda with one of these and it worked a little bit. But still leaked. haha

With this strap, I will easily be able to disconnect my pipes in my exhaust. I have been using an auto zone coupler and normal exhaust clamps. That crimps the pipe and makes it very hard to remove once it's crimped down. Plus, you need a tail pipe expander and it gets to be a pain. These strap couplers sound like the answer for me.

 

well I just got off the phone with dynomax, they are claiming that since this is SS, it can be used to attach header pipes to one another.

I'll be testing that theroy. My EGT's have been ~800 deg c

 

been meaning to update this thread. These style clamps http://static.summitracing.com/globa.../wlk-33226.jpg are not air tight. I am getting a decent size exhaust leak at both places I am using them. I have them as tight as they will go.

 

thanks mike, I may not even try mine.

 

I forgot to add my experience with these. I think they work GREAT! I've unbolted my muffler a couple times since I got it and it seals great. Just get out your vernier caliper and make sure you are trying to butt two pipes that are EXACTLY 2.25" in OD. I got the 2 1/4" strap coupler.

As a matter of fact, the OD of my stock Bpipe, just before the muffler, is 2.125". I found a cheap exhaust coupling at Pep Boys with an ID of 2.125" and an OD of 2.25". These are exact measurements. So I cut the coupler from Pep Boys the long ways so that is looks like a "C". I used this to shim it up. Now, I strapped on the 2.25" Dynomax coupler from Summit and it worked GREAT! I was very surprised. So my advice, make sure you have the EXACT size and it will work. From studying the product visually, it won't seal 100% if you have a pipe with an OD of 2.3" or 2.2" (considering you have a 2.25" coupler). So find a way to shim it up and it will work great.

 

Sounds like you are using butt joints, but I am using lap joints.

 

btw mike, mine are lap joints... and just like you, they leaked, and didnt hold the pipes together.

 

did you guys use any high temp rtv on the clamp that might help stop the leak

i know lots of people using hightemp copper rtv for all sorts of exhaust flanges and even header gaskets with great succes

 

Ohhh. I have the butt strap coupler and it works great for two pipes that are equal size.

 

copper RTV works with a gasket or something....but if it has direct exhaust pressure on it then it'll blow out.

 

yeap

I sealed my header gaskets on the mustang with high temp copper rtv. Leak free since 2003

 

copper rtv is very inexpensive too.

 

So Mike what's the word? Like or dislike?

 

mustang guys are the people that ive read use it alot as a gasket REPLACMENT AKA they use no gasket just copper rtv and the only ones i read about have turbos so the exhaust pressure would be higher than an NA car

 

Me? I got exhaust leaks...

 

Oops. Bags, I mean Bags... what's up? hehe

 

I have yet to use them.. house projects are kicking my a$$..

I was going to not use them and just weld after what mike said.

 

Can you guys just use the butt joint strap coupling I used? It works great for me. Since I don't have tubing that has a sleeve on it that fits over another piece of pipe, I just used the butt coupler.
