Damn, everyone of these is rattling. I wonder if I should even bother unboxing mine.

 

For those of you that know - how does this setup compare to a Greddy SP2 in terms of dB and drone ? I am getting an SP2 from another local member with the hopes that it takes it back to near stock levels.

 

I spoke with Lisa of warranty 1 734 384 7898 ext. 7781 @ dynomax

long story/short: they are sending direct a corrected muffler.
Dynomax claims all mufflers in their stock are corrected.
As of last Friday Jeggs was under the impression they would get a drop ship from dynomax 6/22

much better thoughts than when I called their contact number and got a "no longer on service"

 

i am curious to see if the revised will be any better... please more reviews

 

I called Jegs this morning and they said Dynomax didn't even want the old one back. Jegs gave a new invoice number and said they would ship a corrected one when they get it. Should I be calling Dynomax directly? I'm not sure if you are saying you can get a new one faster that way?

Thx.

 

its your call.. you might ask Jeggs when they will get the new mufflers.

 

you would think that DynoMax would test it alittle better than this. you know they mut have thought of someone using it on a cammed V8.

 

They are replacing mine as well Apparently there is a date code on the label of the box (mine was 0909355) and anything before 0910121 is part of the known issue, hope that helps those of you that have one and haven't installed it yet!

 

Did you call Jegs or Dynomax? Email?

 

Dynomax directly.

 

I'll put that on my agenda for tomorrow. Thanks.

 

Sorry can any of your quiet exhaust gurus comment on the Greddy SP2 ?

 

So did you already ship the defective one back to Jegs?


Did you ship yours back to Jegs and then call dynomax? Mine ends in 0910089. So mine is gonna need replaced as well.

Should I deal with Jegs or Dynomax??

 

I would call Dynomax, since they apparently have them ready to go in stock. I have not shipped my defective one back and apparently don't need to.

 

Same as above.
