Wierd noise

So recently woth my new exhaust i can hear iit even more when i press the gas i get this like raddleing sound from my engine? Like a tik tik tik
Super fast ... It still feels like it has normal power and everything I just hate the noise.... Like a constant rattling?
Anyone know or think what it could be?

Thanks

Did this only happen since you got a new exhaust? Could it be something that was there all along and you just never heard it?

My flapper valve on the intake snorkel makes a rattle. Check that.

Collapsed valve lifter? (just kidding)

Does the speed of the rattle follow the RPM, or is it constant?

It follows the rpm or whenever. I push the gask its like a super fast thuding . It could be a leak but its coming from the front of the car ? Mabye the headers but idk . Cause i can hear the exhaust from the back perfectly. Just ill use gas and it like thuds with the rpm slightly and how ever much gas. I push down.

With the car parked and the hood open you can work the throttle and listen more closely, perhaps.

Your distributor cap is on crooked. You'll need a new cap and rotor now.

If that proves to not be the issue, then check your timing...

I have 2 FB's with new RB exhaust systems that make an odd noise too. Its unusual, but according to RB is the new mufflers not being broken in. /shrug

But they also sold me a carb last year with a fat crack in the main body that was "tested" and told me all sorts of **** was wrong with my car, so ill never know haha
