hey guys, i just had an rsr axleback installed onto my itr mid pipe. i've noticed that when i start the car, i hear small popping noises like a backfire. i only notice it when the engine is still cold and is reving at about 1,500 rpm. i can also hear it when i'm slowly driving off. what's wrong and how can i fix it? thanks

 

Nothing is wrong. My exhaust does the same thing, I think it's kinda cool.

 

you sure?

 

Mine does it too, it sounds interesting I don't think it is something you have to worry about.

 

thanks for the replies. i guess i'll have to live with it.

 

mine too no worries

 

as does mine, i dont have a n rsr but hey.i believe its just back pressure flowing un restricted.
