After installing my HFC's and exhaust I noticed this weird noise. Well i took everything off and re-installed it. It seems to be coming from the X-pipe. And only at 2,000 RPM's. Anyone know what it could be

I'll add another vid later tonight.

sounds like a heat shield but I know they are not there after market weird.

 

Don't have access to youtube at the office... Can you explain the noise? Rattle? Clunk? Buzz?

 

are you surfing at work? bad oyou

 

Nope... That was my summer job about 6 years ago... Hehehe

 

maybe an exhaust leak but its hard to tell from the vid. It doesnt sound like a rattle so its probably not the pipes hitting the heat shield.

 

i have that sound too... can someone explain that...

 

I've never heard an exhaust squeal like that before. I triple checked all the connections and everything is snug. Maybe it's just the way the exhaust is traveling through the x-pipe.

I also sent an email to hottexhaust to see what they think. We'll see.

 

i have this sound but not from x-pipe it comes out from the back.

 

can you take a drive by and rev vid of the magnaflow with hfc?!?!? please!

 

I also have the same sound after I installed FI HFC.
I never had this noise when I had intake & exhast so
I'm sure it's coming from HFC. It kinda sound like
air being sucked in.
I also wonder why...

 

I have a rev vid . I just need to do a drive by and then upload to youtube. I should have it dont tonight or tomorrow.

Sound about right...lol. I am gonna remove the magnaflow exhaust and put the stock back on this week and see if it still does it.

 

Dipstix,
I think taking the HFC off will be easier step.

 

damn, that is strange, does the other pipe move or just the one side? show me tonight.
