So i want to use a 3" vibrant stealth muffler and a 18" vibrant resonator but i dont know where to find 3" exhaust piping. Is there a place online that sells cat back kits that dont include a resonator and muffler? Could i just take the muffler and resonator to a local muffler shop and have them make me custom piping? Whats the cheapest way to do get this done?

 

That's the EXACT SAME muffler and resonator i'm using,& i went w/a VRS Exhaust kit-it's exactly what you're looking for & is cheaper than KTeller.You have a choice of stainless or aluminized mandrel bent kits(w/flanges,hangers,etc.) that just need to be welded together.I also have a 2.5" set-up w/ a different muffler on another car,and it's held up for over 3 years(both set-ups are aluminized versions(cheaper), i painted both black w/high heat exhaust paint.)IIRC,the tubing kits start at about $190.Hope this helps!

 

dont get a custom piping . it goes from 3 inch to 2.5 . they bend the pipe /

 

i put this kit into my brothers car. 2.5" mandrel bent piping with a vibrant 2.5" offset muffler.

piping was cheap from this place.

does that resonator interupt flow at all?

 

No resonator doesnt affect flow atleast not like a cat or stock muffler would.

Why dont you buy a generic "jdm" catback for your car from ebay. And just take off the muffler and sell the muffler.
You can get one for like $120 an sell the muffler for $30 on crapslist
