yup, mine sounds raspy with the midpipe. I wouldnt compare it to a civic however, it doesnt rasp that bad. From a couple miles away, my car sounds like a street bike that's revving very slow lmao

With a properly resonated midpipe, the raspy and loud sound can be tamed. Look into midpipes such as BHR and Racing Beat Dual Resonated if you want to keep your car catless.

Yes, resonator is your friend.

+1, I am very satisfied with my Racing Beat Dual Resonated / Greddy SP2 setup.

+1 for more resonators!

Adding a turbo would quiet it down even more. You could have a shop cut and weld in resonators for you but have them give a quote first. It might be more effective to buy the Racing Beat or BHR that has them all ready. Good luck.

HEY! I drove a CIVIC once! Annnd nooooo it wasn't too raspy..... Greddy Evo'ed it right
