I have one if those Cx lighting exhausts (Imitation HKS) from ebay installed on my G35, but i just think it sounds too loud. Is there any way i can soften it up a little with either a silencer or something else. And if so, what do i need and where do i get it.

Thank you for your replies.

If you have stock cats, the only way it would be too "loud" is from drone. That exhaust is producing a lot of drone because it only has a very small H pipe. In order to produce enough destructive interference with each exhaust pulse, you would want more crossover with each path.

You can weld an x pipe into that exhaust where the current h pipe is. Take it to your local muffler shop and use this x pipe.

I don't believe anyone sells silencers that fit in mufflers with separated tips.
