ok...think about how bad an ls1 sounds with an open dump...
 

now imagine that in 6 cylinders...my jeep sounds so obnoxiously terrible at the moment

open header ls1's sound sexy. ls1's sound so awesome:nod:

:rofl: Yea.... ok....

stock cars with open headers sound like ****

Putting a cat-back on the heep Eric?

- Justin

eventually...but right now the cat is all plugged up so im in the process of hacking it off

sounds better than your boat anchor

i dont think my cam/lts/ory/cutout sounds too bad. wide open sounds nasty and idle sounds nasty. anywhere in between is raspy.

Jeep 4.0 with open exhaust sounds like ass. I ran out of time when I was installing my cat-back, so I had to put the Jeep back in the garage for the night with no muffler/tailpipe on it. It was obnoxious, and not in a good way. :) I was VERY happy to finish the install the next morning!

Sounds like a ricer engine. Inline motors FTL when it comes to sound.

i thought my stock ls1 sounded ok with a cutout =(

ehhhhht wrong.

The only time I enjoyed how my LS1 sounded was when I had TSP TDs dumped with a cam. The magnaflow and cats now sounds ok. Damn this diverted from "on topic" fast as hell hahah

Straight 6 Cummins FTW :rofl:

Oh you're so wrong my friend.....my 76 Plymouth with a slant 6 sounded pretty nice for a POS with a worn out engine and literally NO exhaust. Pipe between cat and exhaust rusted off and I yanked them....guts of the cat fell out. Sounded like NASCAR ;)

Slap a flowmaster 40 on a 4.0L Jeep Engine. You know what, clamp it on, because you will want to rip it off bare handed when you hear how bad it is.

hahahaha

it sounds great...it sounds awesome, theyre just struck with LsEnvy. theyre mad at our gas mileage and awesome technological designs which made their motors seem like outdated boat anchors with a toilet bowl for an injection system (gen1) and an ignition system stuck behind a forever leaking water pump (lt1) meanwhile our motors still run the same with 180k miles on them as they did brand new. :twisted:

a cutout is different than open headers, unless you have 2 cutouts, one at each collector

LS1's are ****** sounding engines. I love the performance, but they are raspy and rattling engines. Very few exhaust systems make them sound any good and open pipes just sound like ass.

-Tim

I beg to differ.

This is my friend Rob's car aka Slaptastic on here


http://www.youtube.com/watch?v=Tf3ARYLCAaM TDs, no mufflers or cats

Yeah, sounds horrible.

Like I said, the performance is impressive, the exhaust note is crap.

-Tim

yeah except for that piston slap :lol:

but thats "normal"

They sound good on video but in person that sound is ear piercing. F' that put a full exhaust on and save the hassle.

i think theyre the best sounding gm motors.
