Exhaust sound

dice_980 · 11-11-2014, 12:58 AM

Hello all I just recently installed my VRSF Dp's, I kind of like the sound but then again am not completely satisfied with it. My first exhaust modification was a muffler delete which I loved because it had a deep note to it. Continuing I did the PE mod to my exhaust replacing both perforated outer piping to solid piping along with an X-pipe which I liked as well but not as much as the muffler delete b/c once again of the deeper note, and just recently replaced my stock dp's with VRSF dp's but it has lots of rasp I installed them myself and am sure everything was fitted correctly. If anyone has had the same problem as me what have you done to make it have a deeper note.

Did the waste gate rattle fix and now is sounding much better definitely like it more, not sure if that did make a difference or it was just in my head but definitely better.

Its pretty common to get lots of rasp with the mods you listed there. I'd throw some extra mufflers on there if you want to keep the catless downpipes.

I noticed the rear of my exhaust the clamp is not there so that must be making a noise as well don't feel like spending ~25 for it so I will make one

lots of mods to come still

, nothing can be done for now it's at the shop getting the door actuator replaced along with the AC vents since the little levers broke off.

Why didn't you keep the muffler delete if you liked it so much?

Well when I didn't have my DP's on and had just the PE mod it was too low and preferred the muffler delete. Now with the DP's on it sounds louder. The first time I installed my DP's I didn't tighten them well enough and air was escaping making a weird noise but now that I have reinstalled them properly it sounds better.
