3.5" resonator options

DieselDakota · 04-21-2015, 08:31 AM

I just spent the last couple days fabricating a 3.5" exhaust for my friends FD. He just swapped to an EFR 8374 and its a little loud for my taste (as in will attract unwanted attention). I'm doing a nearly identical setup in my car and will be fabricating my exhaust in the next couple days. I want to add in a resonator now rather than modifying stuff later.

What are your guys experiance with resonators? What companies work good? I'm assuming most won't last more than a couple years and will be need to be replaced every now and then?

It's for a 3.5" system made of 304SS

looks like some of the options that pop up are:

Borla XR-1, available in 3.5",seems there are lots of types, and some of the prices are up into the 300-400$ range which is alot considering other types sell for 100-200$, but they seem to use steel wool packing instead of fiberglass, might last longer.

Raceing beat, not available in larger than 3",

Vibrant resonators, Aaron Cake said he had some success with their "ultra silent" style resonators however these are not available in 3.5" they do make a traditional bottle stye resonator in 3.5". http://vibrantperformance.com/catalo...oducts_id=1703, very cheap at 100$, need to look into this option more.

the borla's seem to be the most recommended but the type/part number isn't usually mentioned

I have ran borlas. They sound good but i think nothing can beat magnaflow.
And to be honest the 4" magnaflow i picked up is top notch quality.

Im looking into installing a resonator here pretty quick too.. its at the limit of bearable, and I woukd prefer it to be a atleast a bit quieter...
