Walker 35129 Exhaust Spring Bolt Kit + 31378 Exhaust Gasket

Fast shipping! Works good!

2000 Honda Civic LX, D16Y7 engine230,000 miles on original forward "A" pipe, about 75,000 miles on OEM replacement "B" pipe (both were subjected to Minnesota winters and road salt).Other than rust on the used parts, the new bolts and springs appear to be identical to them. Of course, the original rusted springs were slightly shorter from use; the replacement spring ends were tapered just like the originals and fit squarely against the pipe flange and bolt heads.The connector gasket fit well after I cleaned all metal mating surfaces thoroughly of rust and scale and did a few more things: after placing the female part of the gasket onto the male A-pipe end, I inserted it into the female end of the B-pipe. I drove the gasket farther onto the A-pipe by gently tapping the B-pipe flange with a hammer. Just to be safe, I alternated sides of the flange, left and right, with every other tap of the hammer until the gasket stopped moving forward.Using VERY LARGE CHANNEL LOCK PLIERS to bring the pipe ends closer together, I compressed the connector bolt springs on the connector bolts far enough to start the nuts. Just because it is my way, I applied high temp anti-seize compound to the bolt threads (probably won't make a difference after another winter). I also installed 5/16-inch stainless steel washers between the nuts and A-pipe flange to help the nut turn and protect the rusted flange from the turning nut.60 miles of driving later, the connection remains perfectly quiet.

I wish these listings would have the bolt specifications. I purchased other bolts and they were the wrong diameter or thread. So, I gambled on these because they are the same brand as my Catalytic converter even though Amazon said they would not fit my vehicle. So, here is the scenario...I had ordered a new flex pipe and catalytic converter. Upon arrival I installed the catalytic converter and everything was great. However, I quickly discovered that the flex pipe did not fit correctly even though eBay had said it was compatible for my vehicle. The new flex pipe came with bolts that were the wrong diameter as well. I called around town and finally found a flex pipe from a local vendor for 40% higher than what I paid for the wrong pipe, but I needed to have my car back so I paid it. The new plex pipe came with nothing, no bolts, no bolt springs, no gasket. Only the pipe. The other gasket, bolts, etc did not fit. Existing hardware was worn out or broken during removal and could not be used.Next, I called around and was able to locate a gasket in an AutoZone two hours away since despite many auto parts stores nearby, none of them had it, but none of them had the bolts/springs. So, I searched the internet and found lots of options, but eBay and Amazon always said they did not fit my vehicle. None of the listings had bolt diameter for me to verify so I gambled and purchased multiple bolts online. Fortunately, Amazon has pretty quick delivery, but it still meant waiting until the next day. I tried two bolts I had received and they did not fit very well. I was very frustrated and considering doing some customization when this bolt set arrived. Amazingly they fit just right for my Walker Catalytic converter on my 2012 Acura TSX, and now I am back on the road. They also came with springs and nuts which prevented the need for further searching.

We bought these bolt to go with the Walker 41725 Exhaust Pipe 2.75" Inlet (ID) 2.25" Outlet (ID) and Walker 41722 Exhaust Pipe 2" Inlet (OD) 2.25" Outlet (ID). They do not work together, they are too short. Amazon gave it as a companion, as "frequently bought together," and they are not. This is not a bad review on the bolt, I'm sure they are great when used in proper application.

I hate spring bolts. Not these ones specifically but the entirety of the bolts that are springs. I tried using normal bolts and it turns out these are necessary to allow your exhaust to flex. Now since I didn't use these my exhaust makes tons of noise. Just use the spring bolts. Some day I'll put them back on my car and my exhaust wont make any more noise. But not today.

This was needed for my 07 Nitro , worked perfectly.

very good part great seller

easily stripped the thread on the bolt trying to get the flanges lined up, they should be stronger

Installation was very simple and they fit without and issue. If you're replacing your exhaust I'd recommend ordering these as the original ones will probably snap when you remove your exhaust if its rusty.Overall, these worked as intended and I would recommend

Pésima calidad, "Echo en india", los resortes mas cortos que los originales, los tornillos se barrieron en la primera apretada, tuve que reusar los viejos.No tires tu dinero el producto "NO" sirve

These bolts and springs are made to the GM specifications in China. Nice reproduction and I am confident they will be fit for purpose.

These worked well on my exhaust. I do wish you could adjust the length a bit. Because my flanges were so corroded , the available tension was just barely enough to seal it . I think a guy could take a grinder and take a few mm off of the pin portion(non threaded part) as needed.All in all, it was nice to have this replacement. Cutting off the old ones was nice . I surely would have set myself up for disaster trying to reuse the old ones.

Good quality
