Exhaust sounds during deceleration.. Question
When I bought my car bone stock. I could rev the motor and no sound was noticed when the engine wound down. After an intake mod and a tuning mod, the exhaust burbles and pops after a rev and deceleration. I don't know if pops is the right word, but I think you know what I'm saying. I think its totally normal but what causes this. Rve Rev Rev then blah ba de blah on the wind down. I think its more of a backpressure thing but why did it not do it when stock. No exhaust mods done at all.

Yes, it is common on stock exhausts. Some after-market muffler systems eliminate it without an X-pipe and some still need an X-pipe to smooth out the air flow. Magnaflow does not need an X-pipe unless you want to turn down the volume. Corsa's sound better with the X-pipe and will pop without one.

I still have to with the X-pipe.
Im having a cam installed next week. Lets see if that and a tune help it. I doubt it. The better flowing exhaust, the more popping I think you'll hear.
If you think your going to spend 300 bucks and the popping is going to go away, save your money
