You guys all must be obnoxiously loud!

I've been running a Corsa Sport with an LM2 as a resonator since I ditched my cats and it sounds GREAT. Took out all the rasp, at all rpms. Had this setup for about 3 years now, on a daily driver through Michigan winters and no corrosion!
The loudmouths are like higher quality stainless Dynomax Bullet alternatives IMO.... although recently I've seen some threads showing newer Loudmouths that appeared to be manufactured more cheaply and possibly a bit inferior to the older LM's...

 

I think I'm just gonna keep the 10 series, I should be ordering my LT's sometime this week if the paycheck is looking good!

 

Are you keeping cats?
If not, expect your exhaust to get WAY louder and WAY raspier!

 

I was also looking in to the Dynomax bullet? which would sound the best out of the 2? with the least drone, with stock manifolds and cats, my 10 series has no drone at all.

 

This is a 4'' Dynomax bullet. It sounded great with it just dumped after it, however after I added the piping and dumped it back to and under the bumper, it had the most ridiculous raspy THWAP at part throttle. I finally had to get rid of it for a bigger muffler. However on your set up it may not be like that do to not putting the power, exhaust flow through it. If you decided on it, I would mount it as far back on the exhaust line as possible.

I have LTs with the 10 series and no cats and its loud but I'd trade my 10 series for the LM 1s..

 

I had no drone with the loudmouth I, but did have a small amount of drone with the dynomax bullets I ran. The bullets were quieter too, I think I had the 16" long ones.

 

I have that set up on my truck, I could get you a vid if you want. I have a vid of a burnout I did a while back... Might be kind of hard to hear it but here's the link
