ok i just installed a 3" downpipe, 3" manga flow calaytic" 3" cat-back exaust, and finally an APEX N1 exaust. My car is an evo. It makes a rumbling sound at the exaust. I hear some other say with turbo cars it's like that. Is this true. To be honest it doesn't sound smooth. My friend says it sounds like a " RICER" trying to be fast. I dont' know what that means but u get the point. Thank u in Advance ........

 

Mine sounds like that. Its not a smooth sound.

 

i think its normal. plus there is nothing ricer about our car. unless you did something.

 

i have the blitz and in the morning it kinda rumbles, its an uneven sound, but i like it

 

Wow, I've never heard of this rumbling stuff. Maybe it's because I only have a cat-back, but my exhaust sounds perfectly smooth all the time.

 

turn your ac off and depress the cluth...

 

ill post a video of mine in the morning if ur still worried bout urs

 

Mine is completely stock, and I hear little burps and gurgles out of it all the time. nothing to worry about

 

Thank u could please

 

3 inch piping all the way back means rumbling..rumbling sounds good..its normal..even with my magnaflow muffler mine still has a throaty growl/rumble to it..people will know you're not a ricer if you dont act like one and if they know ANYTHING about cars they will know ur not some civic dx with a bolt on muffler

 

u mean on of those UNIVERSAL mufflers

 

My car rumbles and sometimes skip- maybe its because of the cams and no cat. Its normal dude dont sweat it.

 

its fine
