ok i have LM1 on my trans am has a mild cam(zz4) shortie headers, i have the pipes out the back with duel exhaust and everyone knows how LM sounds i was thinking of right before the axle put a cutout and put a turndown on it but keep my tips so the sound still comes out but will the rasp smothened out by the turndown? am i right or will the rasp still be there if i do a turndown and keep my tips, or just a complete turndown?i always thought turndowns smoothen the exhaust out because if gets deflected in the ground. or another option was get the longest powerstick i can fit in the I-pipe and do that.

Uh....if I understand correctly.......the answer is no. I will be much louder turn downs or not. Just get a better muffler than the LM, lot's of choices out there.

Ive heard turndowns give you alot more drown in the car, but unless you add mufflers or cats the rasp will still be there

i use to have SLP LM dumped and it was ridiculously loud and sounded like ***,had no tone to it just a bunch of noise until you went WOT

You'll see no performance gain using a cutout on a LM as the muffler actually out flows the exhaust tubing.

It will also be louder with no muffler. Either run CATS with the LM or swap the muffler out for either a Magnaflow bullet (PM me if you want the part number) or a Powerstick chambered muffler.
