from what ive seen and read the only way to get rid of or at least most of the rasp is to add really good quality resonator(s) and a high flow cat.

i have 2 resonators on my 2.5" catback which starts after the secondary oem cat, hks muffler, oem s pipe, and a catted megan header. and i have 0 rasp

what other exhaust mods do you have?

if you still want your stock midpipe, then get a high flow cat and 22" or resonator.

but dont you have the megan v1 header that already has a cat installed?

yes i do, but the cat on there is crap

SR0529

^ So you have 2 resonator and 2 cat converter. no wonder there's no more RASP

well the one in the megan isnt anything special, and the secondary cat is, well, a secondary haha. but yeah 0 rasp. after i install the turbo ill remove the secodnary cat, and do straight through 2.5" piping, may or may not keep resonators

SR0529

I only have stock cat and aftermarket 14" resonator which replace the stock one. it RASP when starting at 3500 RPM.

I wonder if i put the vibrant Ultra Quiet Resonator (4.5" x 6.75" Oval Body, 10" Long) would that be good enough to kill the RASP?

in the video description it says he has a vibrant ultra quiet installed and im assuming not cats of any kind but its still kind of raspy for my taste. its a lot better then most setups though.

hey its my video! lol (two above)
no I dont have any cats, just the AP and the vibrant reso's. I will swear allegiance to the vibrant tho. I did the catback first...then i got the weaponR header. It was so loud!! and raspy. I ordered the vibrant, It was like night and day!! almost all rasp went away and it even reduced the noise back to what it was before the headers.
I recommend the vibrant to anyone thats doing headers, plus they have all our sizes: 2.25", 2.5", and 3"

SR0529

all I need is one more resonator, I think I will go with Vibrant Ultra Quiet.

Aero 25 is for 2.5" piping. I don't have 2.5" pipe setup.

it was a nice sound clip by the way.

Irish_tc_518

btw my video sounds more raspy on laptop speakers. if you listen to it on real computer seakers with a bass it sounds much more real

xdejablu3x

yeah i listened to it using my desktop speakers with the sub. i was going to do your setup exact a different axble back but the ultra quiet is pretty big. i was planning on putting a high flow cat on and i dont know if that and a ultra quiet can fit without my scrapping it on the road or speed bumps.

SR0529

Vibrant Ultra Quiet is not that big isn't?

xdejablu3x

i remember someone was saying that the only place they could really fit on the midpipe for a almost perfect fit was were the secondary cat was but im not so sure? i really want to have both but i dont want to get the parts and find out they dont fit without problems.

xdejablu3x

hey if you dont mind can you take a picture of where you have your resonators installed? just want to see if i can fit a high flow cat and a vibrant ultra quiet on there.

SR0529

I really want to see too.

quick. lol
