A local shop did mine in 1992. Nice custom job in a few hours. $300. Still works great.

my guy charges 200$ not including the mufflers cant beat that

 

I've got 2 mustangs. 1)has the magnflow kit with Hooker comps, Had someone install the kit - they charged me $150. 2nd car I was trying to save some money - plan on selling eventually. Bought peices from NPD put together myself. Parts cost me a $250. All pipes (incl H) and cheap alum coated mufflers from summit. Was more work than I thought - basically lining it all up was pain. Did not weld just bolted everything up. After reading these posts I'm sorry I did not try custom route on the 2nd one at least for est. But for the 1st car definitely glad I went with Magnaflows. Flowmaster were too loud for my taste (getting old I guess)

 

Like I stated before I had Flowmasters on mine. Switching to Magnaflows and I really like the sound of them (from the sound clips). My mechanic has a friend that does all his exhaust work on the restorations he does. He told me the guy will charge between 140-160 dollars to run the exhaust. Sounded like a deal to me.

With you living in the Netherlands I'm sure it's different than here. I'd still suggest getting quotes from some local shops on what they'd charge to run it if you purchased the mufflers. Cover all your bases as they say.

Oh and I also opted to buy some nice Magnaflow stainless exhaust tips for the looks and just so I don't have to redo something later and pay for it again.

Hope you can get it all worked out, and glad to hear you're going with the Magnaflow mufflers. I think you'll really enjoy them.

 

i have been asking around here and there and the idea is that it would cost me having it done here about 1000euro ($1500) all done with stainless steel pipes) and from what i understood i can bring my own mufflers in.... so al in all getting such a magnaflow kit (http://www.magnaflow.com/02product/s...one=all&id=913 ) ( i definitely will go for the magnaflow) even with shippingcost etc is much cheaper.. but then again... the if the fit is nog very good every dollar spend is too much

I'd have to recommend against the 2.5" system, regardless. You'd have to have one hell of a 289 to need that much exhaust. 2-1/4" is plenty.

 

hmm.. those magnaflow kits are only available it seems in 2 1/2" ( or in 3" stainlesssteel)

if the 2.5" is an overkill.. does it mean a loss of power or something?

From what I've read that is correct Aurthur. Good news I went and heard my exhaust this morning and the Magnaflows sound awesome.

 

Too large of an exhaust tubing creates a lack of backpressure at low rpm's, which throws exhaust pulse timing off and reduces low-end torque. Dual 2-1/4" pipe is enough to support about 300hp (net hp, not gross), which should be more than enough for your needs. Twin 2-1/2" pipes are good for about 400hp, which is likely way more than your 289 is making.

 

ok.. so it won't become the 2.5" ... actually sounds more like i even have enough with the 2" with the current setup of the engine
good thing i i have asked for advice on here else i sure would have gone for the 2.5"
