generally how do the two compare sound wise? not necessarily sound quality but more noise level...thanks

 

somewhat the same in being loud but yes a diffrent tone. Also it depend on where the cutout is located.

 

cutout will be a touch louder i think.

it is typically located under the car which leads to alot more interior resonance.

the LM spits the sound out the back and away from the car, plus the resonator does a little bit of muffling

 

assuming the cut out is welded in over the axle would they be more similar?

 

over the axle?? huh?

you mean behind it?

then yeah they would sound more similar, but there isn't much room for that.

 

well what i meant was 'just' over the axle...meaning, as you said behind it...thanks

 

I'm guessing you really mean before the axel, never have seen a cut-out welded in after the axel on a 4th gen...

 

ehh whatever lol

 

Which one of these do you think makes more power? I have my LM on right now, but I have another setup in the garage that is the stock pipes w/ a flowmaster exhaust but is has a cut-out welded into it. When I ran my car on the Dyno on a VERY VERY cold day it ran 315 RWHP(with cut-out). When I ran it on a very very very hot day it ran at 290 RWHP(with LM exhaust). My question is that is a huge jump and the temps were at cold and hot extremes for the days I dynoed it. What is ya'lls experience with these two exhaust options?

 

the LM should dyno more since it is full 3" pipe all the way with a non-restrictive muffler.

the cutout will be free flowing as well, but if it is on a stock pipe, it is only 2.75" diameter...which is a 16% decrease in volume

temperature, both air and engine cna have a huge affect on power output

i've always read that for every 10deg drop in intake air temp, the car will make 1% more power. so 30deg drop on a 300hp car is about 10hp alone.

you say "very very cold" so say 40deg outside? compared to a hot (probably humid too) day...could easily be 100deg. that's 18hp or so...not to mention small changes due to engine being warmer.

 

I have a cutout on my Magnaflow catback. Soundwise, the cutout is really loud(especially if you punch it) and the sound quality is simply amazing My only complaint with having it before the axel is that it creates a lot more droning racket inside while cruising down the interstate than versus running the pipes out the back with no muffler. Also the exhaust vibrates the car and my center console makes some afwul buzzing and rattling when I am accelerating at mid to low rpm's.

 

i would go with the cut out i love mine sounds good all the time but at low rpms it rattles my center cosole and my dash that is the only downfall

 

cutout, especiall with an electric plate so you can have it quiet when you have a headache or something

 

I had a DMH electric plate on my car. DO NOT go with DMH, the motor fell off of the butterfly plate while I was driving down the road Now I have to call them up to b!tch and whine to get another one. And it fell off after only 5 months

 

the reason i ask is because i have heard loudmouth in person and its pretty loud but i havent heard a cut out in person...i love my 2otl but sometimes i could go for a little more noise...which is where the e cutout comes in
