Need help picking a resonator for my 3in exhaust (only has Megan muffler)
What's the biggest diameter that will fit in the tunnel 4 or 5
And 18 or 24 for the length
Been looking at vibrant
Thanks

 

i had a 6" round 30" long magnaflow resonator on my car, however with the extreme drop i have i bottomed it out one to many times and had to replace it.

have a look at magnaflow stuff, they have a lot of options. if your not lowered too much you should be able to get a 5" diameter in there, and i say go as long as you can.

 

ima measure the catback when it comes and see what size i can get away with

 

bump need more suggestions going to either get a 18: long vibrant or a
18 in long magnaflow with 5" body
