Headers and RPI exhaust = So SICKK!!

mpower03 · 05-12-2011, 08:48 AM

Yeah there is a ton of drone.. I did sound dampen it which helped consjiderably, but there are so many rattles un rough roads and acceleration that I cant stand it. This is only becaiuse of headers and rpi. I just took the mufflers off put the stock back on, and its quiet now, no rattles. Compared to before I thought I was jin a prius it was so quiet. Im goim going to buy new mufflers. I was thinking custom magnaflws.. What did u do?

I pulled out my SuperSprint Race mufflers and put two AR25 resonators with custom tips. My car sounds way better now (used to sound good before too). But the drone is intolerable and I'm driving from SD to Vegas this Tuesday with this setup. (I better buy a pair of ear plugs just in case)

how loud was it with the supersprints? did it create rattles when you accelerated? was there any drone?

Videos are up

By the way, i removed my roof vinyl the day before these videos were taken because i couldn't stand the imperfections from the installation. Will redo again most likely.

LOVE the sound. Thinking about doing headers this summer, but not sure my ears can take the rpi's. haha.

DUDE!!! That sounds SICK!!!!

mpower03 · 05-22-2011, 01:03 AM

it really does sound sick. got compliments all the time... but even with sound dampening in the trunk it created to many rattles when ever it would drone the resonance in my car caused so many rattles. Dont know if it is like this without headers. I sold them and am going to buy some quiet mufflers..
