I took off my obx racing cat back exhaust so that i could install a greddy evo cat back exhaust.

I could hear vtec engage with my obx exhaust and it was loud and my 99 gsr felt like it accelerated much faster once vtec engaged.

now with my greddy evo exhaust i can't hear vtec anymore and the car feels like it doesn't accelerate as fast as it used to once vtec engaged.

can anyone explain why this is happening? both of the exhausts are the same diameter and they both have a resonator on the mid-pipe except the greddy has 2 resonators on the mid-pipe.

*** dyno's

 

all you ddi was switch the exhaust?~ what other mods do you have?

The greddy evo is going to be more deep toned than the lawn-mowing obx, therefoe you vtec engagement might not be as loud.

 

My only other mods are AEM CAI. I have a stock header and stock cat.

 

it's all in your head

 

is the greddy evo has 2 resonators ? and is it really low tone ... im plannin to get it
