Question about resonator on exhaust systems

[plee3]

I was wondering what is the resonator on your exhaust for??? Im going to purchase a full exhaust system today! headers, down pipe, flex pipe, maybe an apexi muffler (really I like the ricey one I have now) and I was wondering what is the resonator for???? Do I need to have it on my car??? does it act like a secondary muffler?? One more question, what size exhaust pipe would be best for my CB7?? 2 inch?? 2 1/4??? 3 inch???? Oh by the way, My engine is the F22A1 so you guys will have an idea on what im working with. One more thing,I completed my auto to manual swap last week!!! My car is no longer auto!!!! The car shifts beautifully!!!!!! no problems what so ever!!!! I thank you guys for all the information you have posted and I post pics soon.

The resonator does muffle the sound a little, you don't have to have it, but your muffler might attract the police so having one might not be a bad idea, with or without it, it won't affect performance. A good size piping for an exhaust would be 2.25" from the cat back.

the resonator helps cancel out certain frequencies of sound in the exhaust.It will take the raspyness away from the sound and it will give you a little molre back pressure, and i would go no bigger than 2.5.Its fun to shift

2.25 is the best size for a N/A A1, my last cb had the A1 and i had no cat no resonator and a 2.5 cuatom pipe all the way down with a ceapo ractive pipe and let just say...I hated it!!!! Got 4 tickets. and it pissed me off on my trip to NY and back. Sounded like a bee fartin into a tuba.Go headers, no cat not resonator to a stocky.

So deleting it would give me more of a ricey sound???

what length? i've seen 10,12,18.does the length make a difference?

[CB7Jay1]

Yup. trust me if you like the deeper, throaty sound, then go with a resonator. My boys teg has duals and header and he brought it back to the shop and put resonators on. It sounded so much better, and it wasnt poppin.

[CB7Jay1]

10" magnaflow or even a chepo would do.
