look at LMC truck company.. they have stock style dual cats and dual exhaust for a 5.7 (350cid) but they'll fit on your 305cid... that is if your 305 is a truck
Catalytic converters are located up towards the front of the exhaust system - typically right after the pipe comes down off the engine's exhaust manifolds. If the vehicle has a single exhaust system, there will be a "Y-pipe" bringing the two exhaust manifold pipes together - the catalytic converter will be just past this. If the car has dual exhaust, there will be a catalytic converter for each.
It is illegal to bypass the catalytic converter and besides your engine will not run correctly if you bypass or remove the converter.
It is in the exhaust manifold where the manifold pipe connects to the catalytic converter. Actually, there are two, one in the exhaust upstream of the catalytic converter and one after the catalytic converter. This is true of any vehicle which is OBDII, pretty much anything made after 1996. V-6's and 8's will haveat least 3, one for each bank plus one after the converter and as many as 4, if it has dual exhaust and dual cat's
I have a 1987 Chevy Silverado 350 tbi that runs just fine without the catalytic converter. I run dual exhaust from each side of the engine with glass packs, has more power and sounds great.......SES light comes on but will go off.......
True dual exhaust is better for performance. Most cars on the road nowadays have the "fake" dual exhaust - tips only. They feed via the catalytic converter then after the rear axle - they branch into dual (or Y shaped) thus making the appearance of dual exhaust.
not a true dual exhaust. most cars had two piped that fed into a single catalytic converter, then a single 3 inch pipe out and over the rear axle. some cars had an option of "dual exhaust" where each exhaust manifold fed into its own catalytic converter, then into that same single 3" pipe. some guys have fabricated true dual exhaust systems for these cars....it takes a lot of work to get two pipes over the rear axle and out the back of the car, but it is possible.
A catalytic converter is designed to burn any raw fuel or other hydrocarbons that get past the combustion chamber. If it's large enough to handle the exhaust, it's ok to use an aftermarket converter. If you have a single exhaust system, you only have one converter. If it's a TRUE dual exhaust, you'll have 2.
I don't think are multiple types of catalytic converters.What might be different could be where it's located - dependent on if your car has single exhaust pipe versus dual exhaust pipe system.
The 1998 Isuzu Trooper typically has one catalytic converter. However, some models may have a second catalytic converter as part of a dual exhaust system. It's essential to check the specific configuration of the vehicle, as variations may exist based on the engine type or emissions standards.
A cat back system is simply all exhaust system components like mufflers or pipes which are attached 'after' or 'back' of the catalytic converter. Here is the twist... it is quite possible for a cat back system to also be a true dual exhaust system if there are 2 separate catalytic converters, each with its own exhaust system components behind it. Then a cat back system in this particular instance, would still include the components being replaced 'after' the cats. The differences arise when there is a single catalytic converter but with split or dual exhaust components after it. From behind the car, the dual exhaust pipes make it look like the car has dual exhaust, but in actual fact it only has one pipe leading to the cat converter and then has 2 sets of exhaust components 'after' it. Again, any cat back system could be either single pipe and component or dual pipes and components. Most cat back systems were created to allow use of the legally mandated cat converter while freeing up exhaust flow after the converter.More answers:Cat-back is simply a strait pipe from the cat back. The difference is a dual exhaust can still have mufflers on the pipes.Cat-back means whatever exhaust that is dual starts at the cat. Dual starts at the manifolds and duals all the way back. You could have cats in duals if you wished and spent the big bucks.Cat back" exhaust is all the pipe and muffler(s) from your catalytic converter to the tailpipe. it is a must in emissions legal vehicles to avois a ticket if your replacing your factory exhaust. however "true duals" are very cheap and are nothing more than a pipe from the manafold or header, to the tailpipe, no mufflers or cats.
there should be two (or four, if you have a dual exhaust set up). one just before and one just after the catalytic converter welded into/onto the exhaust. There will only be one, it is in the manifold on the back if the engine.
i believe back then 1 ton trucks were exempt from smog rules...I remember if you had a 1 ton u didn't need to get it smogged. I have a lazy daze class c with this chassis and it does not have the converter on it. I believe the original owner had dual exhaust put on right after buying it new.
