best exhaust system?

[snzuloz]

who makes a decent exhaust system, that is preferably stainless, doesn't have an annoying drone on the highway, is 3 inch mandrel bent and doesn't locate the muffler under the rear seat area. i know that atr's system was ok, pretty loud and tends to drone, anyone know of any other systems available. would prefer to have either single muffler/tailpipe or dual look, no cat in car just needs to hook up to downpipe.

86 g.n. too many mods to list.

They sell them as well. Price is around $500.
They sell the 4 inch oval connection for $95
if you wish it have your own pipes bent.
It's basically a four piece setup (including muffler) but
everything can be purchased individually.

Cottons 2 1/2 Stainless.

I bought The stainless 2 1/2 dual exhaust with stainless polished magna flows mufflers, and everyone that has heard the car likes it. Its a lil costly but unless ur jumping ramps it should be the last exhaust u buy for the car.

How are the magna flows -very quiet? any drone?

 

[Adam Connell]

If I was looking for the quietest performance system what would it be?

I have a flowmaster cat back that came with my car, but Im sure there is something better out there that is quieter and flows better. I really am shooting for a street sleeper... All I want to be heard is the turbo and a very hushed agressive exhaust tone.

Stock exhaust with electric cutout.

Quiet and NO drone

My gn came with duel magna flow-tips exit 45deg. behind rear wheel,mufflers are 10in in front of rear axle. No drone and quiet.
