jus got new exhaust system from new megan headers, new obx cat converter, gently used megnaflow cat back and it sounds clean excpet for a rattlin noise sounding like theres a rattling tin can when i gas. anyone know what i can do to get ride of the rattling? thanks in advance

 

how long has the magnaflow catback been used for? it could be that the muffler canister is getting old. I know that my greddy evo does this but only cause its getting old and the inside if probably breaking up...

 

ok the catback has a resonator in it, that gets loose,
take the silence out weld it around an it will be fine, usually after 1 year all exhaust do that if they arent super high quality.

 

i dont know how long the cat backs been used for but still looks pretty clean from the inside.

so right now i need to open the resenator and reweld the inside? it also sounds like its coming from right under the drivers side floor?

 

so it the muffler or the resenator that i need to repair/replace?

 

yeah take of the mid-pipe with the resonator, and shake it u will hear tha rattole look inside u will c the insidebaffol of resontor loose, get that welded and it will be all good !

 

my whole cat is one piece the pieces is my headers + downpipe and my cat converter then my whole cat back is one piece any other way to check?

 

dude its your muffler bearings that are bad

 

whats the muffler bearings?

 

just fricking un-bolt the section with the resonator and u will be able to shake it andcheck

 

like i said ^^ my whole cat back is one peice...

 

so its a custom exhaust system like mine.

all in one piece.

 

yea it's a custom 1 piece

 

did you put in all the gaskets? mine rattled like a tin can when my friend put on my header because he forgot to do those...

 

yes and all new

 

check those rubber things that holds the whole exhuast up. mine rattle really bad 4 months ago when i'm in high speeds, but thats only because one of my rubbering was way off and the exhaust hinge was hitting the car hinge.

 

It might be as easy as just checking to see if the bolts holding your exhaust aren't coming loose. Crawl under your car and check to see if they are. Happened to me on my car. I finally had to loc-tite the bolts. Now thre's no rattle. Always check the small things first. g/l

 

will do all that and update as soon as i can thanks guys!

 

yea dude my 93 del sol does has that rattling sound when hits like 1200 or 1300 rpm it makes a nasty rattling sound too but mine sound like its right behind the driver seat so idk wats wrong with mine either
if u figure out ur problem maybe u could tell me wat was wring with urs so i can try it on mine cause that sound is nasty

 

any heat shields? i had that on my stock exhaust and just bent it out a lil bit and presto the noise was gone.
