I would like to know what the stock exhaust size is on a 1997 Cobra. Is it 2 1/4 or 2 1/2? I think it is 2 1/2. We are thinking about buying a pair of mufflers for it, but I need to know what size before we buy them. I can't get a straight answer from Summit or Jegs etc. What size should I get? What would sound best on a convertible? I was thinking stainless 50 series Flowmaster. This is for a car that is daily driven by a my dad who is in his 60's. Thoughts?

IIRC, the factory exhaust system is 2 1/4" diameter. Take a look underneath and make sure the stock system is still in place (disregard if you are the original owner).

Sound is a very subjective matter, what sounds good to your ears may sound like garbage to another person's ears. Select the style that suits you (chambered mufflers = old school sound, straight through mufflers = more exotic sounding). Listen to different exhaust systems in person first (ie - car shows, cruises, etc) before you buy a new set of pipes or mufflers - it's the best way to judge it for yourself...

G'luck.

Hey guys, thanks for the information. We plan on keeping the rest of the exhaust stock. I noticed that the stainless 50 series Flowmasters have nearly the same size dimensions as the factory mufflers. So, that would make swapping them out easier.

I usually prefer the sound of chambered mufflers. However, this is on conventional pushrod V8s like my F150 and 5.0 Mustangs I have heard. I am going to run original 40 series on my 65 when it is drivable. I just didn't want my Dad's Cobra to be obnoxious and drive him nuts. That is why I was thinking about the 50 series.

I have heard several of the modular Cobra 4.6 with different exhaust setups. I just never knew what they were running for exhaust. I have heard a couple that sounded horrible though. One guy I talked to said that he had Magnaflow and no cats. His car did not sound good. I will try to listen to a few more and find out what they have on their cars at the local Saturday night cruise in / car show we have here.

I know I'm reviving an old thread but we still haven't changed the mufflers on the Cobra.

I used to be a fan of Flowmaster. The more I hear it and the more I ride in vehicles that have it, I can say that I actually hate it now. It sounds exageraged and hollow and drones. I got rid of the crappy Blowmasters on my 65 and went with Dynomax Ultraflo on it. I am considering Magnaflow possibly for the Cobra. I have Magnaflow on my F150 now and really like it.

I'm curious of something though. What is the actual design of the factory Cobra mufflers? Are they made like a turbo muffler? I'm just wondering if we are really going to gain anything by changing them. I can say that I would rather have them than Slowmaster crap.

Sweet. That sounds like exactly what we are looking for. Does it sound like this? Do you happen to know which ones you have that are the same dimensions as the OEM mufflers?
