I've had my hahn catback now for 8000 miles and I just recently start to notice the tone change a lot. Its starting to get raspy when I rev it and under acceleration. It sounds like buzzing and its rly pissin me off. Has anyone else had a similar problem with their hahn catback?

 

I thought mine was starting to sound like that but then again i thought it was just me.

 

it used to sound really good, it was loud under wot but had a nice deeep rumble, now its geetting louder and louder and sounds like ****. Is there anyway to contact hahn? i hear they are hard to get in touch with.

 

Interesting... Have you checked for an exhaust leak ?

 

Or your catalytic converter... when a cat begins to be clogged, this can do that.

 

i have no cat

 

Greattttttt I hope I my hahn still works ok when I put it on

 

hahns catbacks are junk, had my muffler and res blow out twice, they replaced it once, I replaced it with a dynomax super turbo muffler and never looked backl

 

i take it it sounds good with the dyno max still?

 

Don't expect much help from Hahn they have really bad customer service... Speaking from experience I had the same problem but it happened after like a week and after fighting them for like 3 months I finnally got a free replacement axle-back.

 

its probably a bitch to weld stainless u think exhaust shops would do that?
