Walker 35129 Exhaust Bolt and Spring for Honda Civic

This is pretty straightforward but these things work just like the factory ones and fit just like the factory ones. But at a fraction of the cost.

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.

Very good product, I recommend it 100%.

Worked well, decently priced, easy enough to replace the exhaust bolts I had to replace.

2000 Honda Civic LX, D16Y7 engine 230,000 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.

perfect fit for a 2007 Honda Civic LX Coupe.

If you live anywhere that salts the roads in the winter you may as well just order bolts before replacing anything on your exhaust. I have replaced the muffler and resonator in my 06 forester twice in the past three years and these bolts have been corroded beyond reuse both times. The tension on the springs is quite high to make installation between the front cat and the midpipe easy. I had to use needlenose visegrips to compress the spring enough to just barely thread the nut on. Depending on your car, buy washers as these nuts fit right through the mounting holes on my exhaust system. Overall, the parts do the job, however I picked up a second set of these for 7bucks total at my local autoparts chain (the one with the shamrock in the O')

Good 👍👍
