Lucky for you, finding the right exhaust stud for your car isn't as hard. For most vehicle's, you'll simply need to check your car manual, or make a quick phone call to your dealer. Don't let broken exhaust studs sit inside your vehicle for too long, you'll never know when they'll snap or break all the way. Browse through our guide and order the right replacement exhaust studs for your vehicle right away!
Just like any bolt or screw, you'll need to get a couple of exhaust studs that'll fit properly. Otherwise, you won't be able to mount your exhaust system tightly, or worse, you'll get studs that won't fit into their sockets at all. You'll have to check with your car's manual or give your vehicle manufacturer a call to confirm the size that you'll need. Alternatively, you could just go ahead and remove your old exhaust studs so you could measure them or take them to a store to find a similarly sized replacement.
Always go for OEM exhaust studs
We highly recommend that you stick with OEM exhaust studs that are made specifically for your vehicle. Most OEM manufacturers usually list the makes and models of cars that are compatible with their products, so you could simply match one that's made for your vehicle. We also advise you to get a complete kit, as opposed to ordering by piece, so you'll have everything at hand when you work on your exhaust, or will have a couple of spare studs for future use. Most exhaust stud kits will run from $5 to $20, depending on the size and number of studs inside the kit. Never use bolts or studs that aren't designed for a vehicle's exhaust system. They are not made according to specification, and could simply break because of the intense heat and pressure generated by your car's exhaust.
How to Remove Exhaust Studs
Removing your car's exhaust system can be tricky. Since most of the parts inside exhaust systems would have been subjected to high pressure and heat, they could fuse into the metal or have rusted shut in the process. The exhaust studs are probably one of the most difficult items to remove in your car, since not only are they exposed to your car's exhaust, they are also subjected to the elements, making them prone to rusting. There are a couple of methods that you could use to remove exhaust studs, so you could save time and money, as opposed to hiring a mechanic to help you out.
Difficulty Level: Difficult
What you'll need
- Vise grips
- Oxy-acetylene, propane or MAPP torch
- Metal punch
Step 1: For this method to work, you'll need to check the exposed shaft of the stud to see if there's enough length for a couple of vise grips to hang on to. This is usually used to remove broken studs, so you may want to use a different method if you don't have enough shaft to work with instead.
Step 2: Using an oxy-acetylene, propane or MAPP torch, heat the surrounding metal around the stud. Do not heat the stud itself. You'll want to expand the metal surrounding the stud using your torch so you could take out the stud itself.
Step 3: Using a pair of vise grips, clamp them on the exposed end of the stud and turn it clockwise. Do not force it out, as it could damage the stud even more. If it moves, apply more heat until you can take it out using your vise grips. If not, then move on to a different method instead.
Left-Hand Drill Method
Step 1: Using a grinder, grind the exposed head of the stud until it is flat, so you can safely drill out the stud.
Step 2: Mark the center of the stud using a hammer and a metal punch, so you could drill a pilot hole into the center of the bolt.
Step 3: Apply some lubricant around the stud, so it can loosen easier later on.
Step 4: Reverse the drill and aim straight into the hole using a left-hand drill bit that's smaller than the diameter of the stud.
Step 5: If done properly, the left-hand bit will loosen the stud on its own rotation. Repeat the process with a larger bit or until the stud comes free. If the stud won't come out, then go on to the next method.
Step 1: Use a drill bit that's slightly larger than the stud itself, you'll be drilling a new hole instead.
Step 2: Drill straight down the center of the stud until you punch through. You'll be able to remove the stud entirely and create a slightly larger hole. You'll need to repair the thread with a repair kit such as Helicoil, so you could install a new stud once you reassemble your exhaust system.
Remember to clean the area around the stud after you've removed it, so you'll avoid getting rust on your new exhaust studs once you fit them in.
