Hi all!
Got a fist size hole blown in the top of the left hand muffler. A bit annoying since its only been on there about a year. They were a pair of Thrush Turbo mufflers I've had in the attic since the nineties and thought I'd throw them on when the originals went poop.
It's a bit (very) loud at present but I like it :D and goes like hell with the hole in the muffler and the traction control switched off. Transforms the car.
Was making me thinking how restrictive the stock system is.

So modified guys, what low restriction exhaust would you replace it with but still keeping it quiet and keeping the back boxes with the stock turndowns.
Would you still keep the stock 2 inch dual pipes or go bigger?

I still want it to sound quiet like a Caddy when cruising since I rent it out for weddings, proms etc here in Ireland but when I'm on my own I want to open it up and have some fun from that LT1.
Thanks all :thumbsup:
regards, Nick

OK since my post I've been through about 3 years woth of exhaust upgrade posts. Took me a solid 3 hours to read it all. You centrainly had some good discussions.
So, from my reading, for a quiet Cadillac-like tone and the best possible power whilst still being quiet the answer is 'the Walker Dynomax 17749's'. Available from Summit or Amazon for 55 bucks a pop, delivered.
However these puppies are 20 inches long, 4 and a half inches high and nearly 10 inches wide. That's big! And heavy! Are you sure they are going to fit under the '94 Fleetwood just in front of the axle??
regards, Nick

Man these guys aren't giving you anything Nick. Wish I had some input, but i am currently running a 75 with a 500 and no muffler and the CC has been emptied. So I don't really think that would be the way for you to go if you are going to have a bride WANT to ride in it.

75 Sled,
Thanks - you've a point there! Always fancied dropping a built 500 into a 77-92 coupe!
Where's Nodih when you need to talk to him!
I've worked out it will fit - made a card template and offered it up and pelnty of room under there so the question remains, will it give me the best flow and still be quiet enough?
regards, Nick
