Merging inventory headers to mill exhausts generally requires bolting well-balanced flanges.
Mating aftermarket headers with inventory exhaust components can be easily accomplished by the morals vehivle fanatic. In the far-flung majority of cases, the header Testament speck in a flange which Testament Friend up to the inventory mid-pipe of the foundry exhaust. Difficulties occur when you are using non-specific headers on determinate cars, or vehicles with engine swaps.2. Use a merge collector if your exhaust headers did not come with one. A merge collector will allow longtube-type headers (which have four individual runners running underneath the car) To gather down to a single exhaust outlet, which you then mate to your factory mid-pipe. These come in a variety of shapes and sizes to assist in custom placement.
Confirm that the headers you are using are particular to the year and representation of your vehicle. Once you hold removed the inventory headers and installed the aftermarket units, they should borderline up with the inventory mid-pipe. Employ the workshop hardware to bolt the header flange to the stock mid-pipe on your vehicle. It is a worthy concept to use a fresh exhaust gasket if your aftermarket header does not come with a replacement gasket.
In these situations custom welding Testament be needed to all-inclusive the exhaust action.
Instructions
1.3. Weld on a mating flange if you have a custom car setup. Where custom work has been done and the exhaust modified so that it no longer sits in the factory location (be it the headers or the mid-pipe) you will need to either weld an exhaust flange onto the mid-pipe that will mate with the headers, or cut the flanges off the headers and mid-pipe, and then use a flex-pipe fitting to join the two pieces. This is best left to a professional muffler shop.
