Lets get this straight first. Any N/A RX-7 is gonna be loud. Even with a stock exhaust, with both cat converters, WITH the exhaust manifold on there.

Well, it is a smart idea to have the intake and exhaust done at the same time. You are going to be adding more air to block, so thus, that would add more power to your block, and it will help run it a little bit cooler. And with your exhaust, you will now be exiting those exhaust gases quicker than a stock exhaust. Are you keeping cat converters, do you have to worry about emissions? If not, get rid of the exhaust manifold, cat converters, and buy yourself a racing beat header.

If you do that to your exhaust, it's going to be EXTREMELY loud, and have negative reactions from all types of people.

 

intake will just make air more free flowing... easier for the engine to breathe.

 

most of the people that have the corksport exhaust said it was good but alot of them said it was to loud

 

thanks for the feed back.....

uummm....i do worry about emmisions and i dont want my car to be extremely loud...i just want it to have a nice deep tone to it....wat should i do???

 

I dont have any cats on my 88 NA and its not too loud at all.

 

will a silencer help????

 

if you want a mid range exhaust maybe apexi n1 or one thats quieter yet racing beat

 

quality wise, racing beat is the best crafted and will easily last the lifetime of your vehicle.
their catback + mufflers are also the most quietest while still flowing faster.
they are expensive but worth the money.
