I'm looking at replacing my single stock muffler with duals. - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Do Grand Marquis 99 have any offsets? Like do the pipe inlet or outlet need to be centered on the muffler?

And for clarification, the stock pipes are 2"?

Are you planning on dual exhaust out the back? If you are, just get the system from a P71 police Crown Vic.

Yes, out the back. I want to buy my own mufflers off ebay to save some money. Is there a offset I need to look for?

I've always used factory parts so that I wouldn't know. Somebody that has done it will hopefully chime in.

I would go w/out the mufflers (like what I have) it sounds amazing (not too loud and not quiet either) and will save you money on by not buying the mufflers. :)

I posted it on these forums before... but cant find it.. so here you are (sample of the sound)

ha haha, In my city I'd be pulled over in a second by the police.

What FlowSound Muffler will fit my application?

http://motors.shop.ebay.com/i.html?E...=p4506.c0.m282 These are flowmaster knockoffs. Flowmaster lost their patent to the 40 series. You can get some awesome deals on aftermarkets.

all you did was cut the mufflers out?

jsuthers · 03-01-2010, 12:08

its a cat-back system...

So what I did was get everything from the cats back removed (new pipes and a H-pipe) that is what my system consists of

XxFordForever · 03-01-2010, 20:54

oh ok cuz what im thinkin of doing is since my car is already dual exhaust i was just goin to remove the mufflers and put pipe what you think

jsuthers · 03-02-2010, 07:43

Iv never done that.... but that would be MUCH cheaper than going the whole new pipe route...

Don't see why It wouldn't work

A lot of my friends were asking why the hell I would want my car to sound like this.... WHO WOULDNT??? this isnt like a crappy car without muffler sound this is a muscle car without muffler (the one kickass loud sound) :-P
