For only the second time since I've owned my Crossfire, I met another Crossfire owner in a supermarket car park. Got talking and he told me he had a stainless steel performance exhaust fitted. Sounded real nice, just the sound I'm after, deep tone and not too loud. He says it is a free flow sports exhaust with the mid range sound (in between out and out straight through race and stock quiet). He was very pleased with it for sound and performance and admitted any gains in HP would only be seen on a dyno.
I took a peak under the back and noticed the muffler box was a round item about 12" x 6", single inlet from the stock Y piece and single outlet to a short Y and 2 tips. He also had the secondary cats removed.
I thought the muffler looked way too small and a little lost in the space ! But obviously works well.
I mentioned my thoughts on the muffler size and he said if he had opted for the quiet version, the muffler would have been twice the size (oval) and was happy the muffler man knew what he was doing.
Are there any guidelines/specs on optimum muffler size ?
It was a very good price and I'm sorely tempted.

I prefer the magnaflow catback exhaust
Sounds absolutely perfect
Do a search here
there's lots to be read about this

 

I've looked at the MagnaFlow, problem is I must have the OEM tips fitted, want it to look standard. Quite expensive in the UK, circa £400.
The spec says 14" x 5" muffler , but the picture looks like it has 2 mufflers side. by side?

Yes you will need a single muffler to modify using the OEM tips
I once had the Ansa muffler on mine with the OEM tips welded and it looked perfect and sounded much like the Magnaflow

I don't believe the Ansa is available anywhere anymore though
It was a Universal fit muffler with the Ansa part # UN0827
You might be able to locate one somewhere searching that part number

Here was my mod photos using the OEM tips on the Ansa muffler

This is what I did...
Same magnaflow mufflers as in the cat back setup but with out tips
Some pipe, an "X", a little cursing and looks good when the car is on the ground and you are walking by
