Recommend me a 4" muffler

Going with another fender dump with the new turbo but can not use my current 3". Think it has a magna flow straight through design. Can't remember what name brand it was. I've got to have a muffler though for it to pass inspection plus can't deal with straight dump. Thanks in advance!

Both a Dynomax Ultra Flow and Borla XR1 work well in that size .. I have used both .. the XR1 was a tad louder than the Ultra Flow's ...

Both ran no different than a open dump at the track

Dynomax seems like a good fit and price. Ill give it a try, Thanks.
