Just wondering what you guys think. I am about to put some true duals on my car and I like the idea of a free flowing and lightweight muffler, but I have heard that they are pretty loud. I have listened to plenty of sound clips on ls1sounds, but in my opinion it just doesnt do them justice. I dont know anyone local that is running them either. I was running an oryp w/ a wide open borla catback and it was really loud. In my opinion a bit too loud. Is this setup with an x pipe going to get me pulled over by every cop I pass? I know its a hard question to answer, but just give me your honest opinion if you believe its too loud or not.

 

too loud? hmm....i wouldnt say too loud, but the drone and interior resonance kinda sucks. they sound damn good though. ive had them on 2 of my ls1 cars. i am partial to the sweet thunders and spiral flow mufflers though

 

just kinda unruly

 

they aint bad at all, turning the turndowns at a 45 degree angle helps. im also partial to the sweet thunders.

 

check my sig

its not too loud

(no cats btw)

 

I daily drove my old 02 Z for a year and a half and it had TSP TDs with the Dynomax bullets. It was just right if you ask me

 

Yes... Never had them---but have heard them on another LS1.

 

I will be goin with the tsp true duals and moroso spiral flows, just because of the interior drone. And I can not afford to get the attention of cops...

 

depends on what is too loud for you? I have tsp td's dumped w/spiral flows and no cats.Not to loud for me

 

Keep the coments coming guys. A few more yes's for bullets and Ill be ordering them. I would do sweet thunders or spiral flows if they wouldnt cost me much power. I just dont want to leave much hp on the table with my new setup.

 

i have sweet thunders, and they are freaking loud i mean my ears ring im not joking, but alot of people say they sound good but i think i wanna go single flowmaster

 

Not on an otherwise stock engine.

 

why not look into the powerpacks?

 

If you ever come to ILL you can check out my car. By the end of the week it will have a custom x, with 3 inch moroso spiral flow mufflers, and 3 inch turndowns. Moroso spiral flows sound the best, in my opinoin and are not to loud. Bullets are noticably louder, and i thought they made the same power.

 

Yes. Friend had 'em, couldn't take it ...

 

Nope, I love the sound of the exhaust. It's just like someone else said, the drone sucks. I don't really have any rattles though

 

It's a little too unrefined for me.


I like to think of Spiral Flows (and Sweet Thunders) as sort of a happy medium.


Don't get me wrong, I love hearing my friend's T/A that has them, but on long drives it gets kinda lame.

 

Over a year now with the Bullets and I dont even hear them anymore inside the cabin. Not that there isnt noise but you just get used to it.

Oh and everytime you set off a car alarm just cruising through a parking lot it will put a smile on your face...

 

Spiral flows... with bolt ons, not bad. Interior drone is LESS than when my friend had his cutout on his car (don't ask how that worked, but with the windows up I can carry on a conversation easily). With the cam, it's a good bit rowdier. And setting off car alarms can happen just by turning on the car now Clip in sig.

I listened to the clip in your sig, and it made my decision. I am going with spiral flows. Your car sounded absolutely awesome with that little bit of cam lope. Not too loud and definitely not quite. Does anyone know if there is any hp difference between the sprail flows and the bullets?
