Default 4" Mufflex

I have it on my 00 WS6 behind ARH 1 7/8 headers and their 3" Y pipe - no cats.

I like the sound of it. Nice low rumble just cruisin round, yet a lil loud at hard throttle.

Though It's not stock cubes either.

The quality of the Mufflex is not the best but it's ok. I had to tack weld the joints as they kept coming loose.

Spintechs are top quality. I had them on my truck. The mufflers are built like tanks.

Honest making a single exhaust set up with a hide away tail pipe seems like it would be easy to do,maybe I should just do a 3 inch into a spintech,what do you guys think,done a lil exhaust work but have never fabbed up a whole cat back

In rereading one of the Exhaust stickys, here's a breakdown of what HP a 3" pipe will support without any loss,

A 2.75” (stock) single system is good for a 310hp engine with zero loss…
A 3” Single system is good for a 370hp engine with zero loss…
A 3.5” Single system is good for a 503hp engine with zero loss…
A 4” Single system is good for a 657hp engine with zero loss…
A 2.25” dual system is good for a 457hp engine with zero loss…
A 2.5” dual system is good for a 513hp engine with zero loss…
A 3” dual system is good for a 812hp engine with zero loss…

Default Mufflex / Magnaflow sound

Here's a short clip of mine I just did. Was not quite warmed up all the way..

Camcorder was about 15 feet back.

It's a lil more mellow then the Spintech. Also the drone inside the car is more mellow.

Might take the camcorder for a ride later ..

Yes that's the Magnaflow 4" straight through.

I'll try n get some drive time with the cam cord. Dunno if it will B 2day.

If you want LOUD,,, I have an open chamber 80 series Chokemaster that really does not sound that bad.

Once I read that the choke master was the worst for flow, I took off the L tail pipe.

I then rigged a long tip for my torch. I cut all the baffles out, so it's just an open shell. When it was behind the stock engine, I really felt a SOTP difference above 3K rpm !

It's mellow cruising round, but WOT, it scream's..

I'll try n post a sound clip of it, but dunno when...

pm'd you. and yes i had TD's for about a year, got a ticket for illegal exhaust, so i yanked them off and replaced with the mufflex system.
