JEEP EXHAUST
We design & manufacture our own header systems to complement the engine conversion business. We started manufacturing
custom headers about the same time we started manufacturing adapters. There was a definite need for headers that would fit the
various engine conversions. Through the years, our designs have evolved into header applications that were most typical. Our header
systems are for non-pollution control, engine converted vehicles.
If your vehicle is going to be smog legal, you will need to retain the original manifolds. Stock manifolds will work equally as well
on engine conversions. Most stock manifolds will require the exhaust system to be routed on the inside of the frame rails.
When doing an engine swap, the exhaust system must be given consideration before finalizing the exact engine location. If headers
are going to be used, we highly recommend that you bolt the new headers to the engine before determining the final engine location.
If you don’t have the headers on the engine while positioning the engine, there is a good chance the headers may not fit properly.
The fenderwell headers that we manufacture are designed for a minimum amount of fenderwell and firewall modifications.
When using headers on a new engine conversion, you will find that the headers do not offer the accessory mounting provisions that
are found on stock manifolds. It may be necessary to fabricate special brackets for the air conditioner, power steering, and alternator
supports.
The chrome headers we offer are not show quality, but are a commercial grade of chrome that will protect the headers from corrosion.
The availability of the chrome headers is becoming limited due to the availability of chrome plating facilities on the West Coast. The
alternative to chrome is a plain non-plated header set furnished to the customer for his own application of finish. The header can
be painted by the consumer using a special heat paint available in most auto parts stores.
STOCK MANIFOLDS:
If stock manifolds are being used on a Chevy small block, a rear dump, close-fitting manifold off of a 1982 & newer low performance
car is a good option. On vehicles that are smog exempt (depending on your vehicle year or state laws), the early Chevy ram horn
(centerdump) manifolds are great for most conversions. On the newer Generation III engines, the stock truck-style manifolds are
a tight fit but they will work in the TJs.
Chevy V6 applications can use manifolds off of a 1978 Malibu Classic. For non-smog legal vehicles, manifolds off of a 1980 Monte
Carlo fit the best.
HEADERS:
Our header flanges are 3/8” thick and all of our primary tubes are constructed with 16 gauge tubing with a 2-1/2” 3 bolt collector ring.
Each design is available in either a commercial chrome finish or a non-plated version, ready for your painting or custom coating.
NOTE: Our headers are not designed to fit Chevy small blocks with angle port heads.
Our written guarantee states that if the headers do not fit your engine conversion exactly as you see fit, then simply return them
for a full refund. You will only be responsible for the freight charges. We do not warranty the chrome plating on our exhaust
systems, and the use of aftermarket header wrap products will void the header warranty.
Thirty-four years of continual
fine tuning and adjustments have made the Advance Adapters headers a choice for all engine conversion installations.
SMALL BLOCK CHEVY HEADERS: The Chevy headers we offer come complete with header flange gaskets, header bolts,
collector rings or clamps for the exhaust shop, and the collector gaskets. All headers can be ordered in a chrome finish or a non
plated finish by adding a (NP) to the numbers listed below.
