How do we know your definition of "sounds better"? Take it off and check it out, let us know.

Your car has three cats in the front, a resonator in the middle, and two mufflers in the back. You said you took off the mufflers, so probably removing that little resonator isn't gonna change much.

Punch out the third cat (that's what I did), or remove it altogether would produce a bigger difference.



1: Mid-Pipe
2: Resonator
3: Third Cat

Check out the exhaust thread under mandrel system...pretty cheap bolt on, comes with high flow cats I believe. Had some bugs the company should have worked out by now.
Theres alot wrote on it just check it out.

Still not THAT great but cant beat free lol. Has a nice crackle. I have a feeling punching out the third cat would help more as mentioned.

No, it did not trigger my CEL.
Sounds pretty decent! You will get better sounds with engine mods and/or tune.

Hey, I just noticed you're from Maine! Where are you? My whole family lives in Sumner, and I own a place near Lincoln.

After several setups I am finally happy with the way mine sounds. Now I can't wait to see the difference with the new motor :cool:
Here's mine

Probably have to say IMO the best sounding bird I've heard on here would be Slidebird. TM posted a drifting video of his car a while back and it sounded awesome

This is the exact thread I have been looking for. I think your car sounds great. Have any of you had any issue with the removed mufflers messing with your cats? I had read once that removing the mufflers would mess with backflow and would eventually ruin the cats. If any of you can let me know---please do. I may do mine this weekend.

Also.....How did you punch out the cat? I am a novice mechanic past oil changes, alt., idler pulleys, MAF, intakes, etc...but have spent thousands on my mustang. Trying to mod up the T-bird myself and cheap! Thanks guys. Great site.

I've posted this in a different thread, but since the OP is looking for ideas.....

The first is exactly what the OP did
http://www.youtube.com/watch?v=TLjaXcF_YYs&feature=related

The second is with true duels with a chambered muffler mid mounted

The third is the current setup with a Magnaflow DI/DO Mid mounted muffler (still true duels) All three have gutted front two cats too, stock manifolds.

Hope you enjoy!

That third set-up sounds like a beast. What kind of magnaflow is that. I wouldnt mind doing that with two SI/SO in the back with third cat ans resonator delete.

It's a magnaflow Duel in duel out 2.25 resonated x. You can find them at summit no problem. Or if you go with the exhaust kit from mandrel exhaust systems, you can upgrade to that muffler. Now remember it goes in the center of the car just behind the tranny and is your X pipe as well. So for me it was perfect since it took care of everything I needed lol. These cars like X pipes to balance out the exhaust pressure. I like spending money on one muffler that does the job of two lol. It all worked out.

Ty for the compliment

I have that same set up, including the rear pipes, but in 2.5. Sounds great.
