I remember how the G35's exhaust sound was so audible and unique, but seems like it was tuned down on the G37. Would like to turn up that signature infiniti exhaust note, but I'm having a little trouble deciding. I want to just add the OEM sport axle back and call it a day, but I'm tempted by others like aftermarket exhausts, and notably the IPL exhaust where there is no Y pipe, no chance of cabin drone, and of course it's cheaper. So I was wondering are there any aftermarket exhausts out there that matches that bill, or am I stuck waiting for another IPL exhaust to be available, or bite the bullet on a sport axleback?

 

perhaps just run an hfc.. they just seem to amplify the stock exhaust

 

Good advice get some Z1 HFC's

 

Muffler delete and get pipes welded in their place.

 

Saw some youtube vids with the HFCs. Might be the prescription I'm looking for

 

I did Berk HFC's first (very raspy) but craved more. I've paired them with a Tanabe Axle Back and it's perfect...minus that darn rasp. I'd go with another HFC if I did it again.

 

Might I ask what's a good HFC to consider?

 

Fast Intentions resonated hfc's

 

Been looking into this. I saw a lot of complaints about vibrations in low rpms or idle due to the lack of the bracket that holds the cat pipe in place. Is this still an issue?
