Looking for the cheapest route to quiet the LM1. A 4x9 muffler will not fit in place of the resonator. I almost ordered the new SLP Powerflo retro kit that fits the LM catback, but it's $300. Has anybody taken the Magnaflow they use in their catback and had a muffler shop use the existing after the axle LM pipes? Looks like you would just add a single 3" over the axle pipe to the resonator and figure out where to cut in the tailpipes. Main thing is figuring out the part number of the correct muffler.
Anybody got a rear underside pic of the magnaflow catback on a Trans Am?
I guess the other option is to remove the LM and sale it to offset the cost of a Magnaflow catback.

I had the LM1... It was too loud and nasty sounding after my H/C intstall with LT's and ORY... Basically we just cut the LM1 system off after the axle so that I still had the LM resonator in the I-Pipe... we then got a magnaflow muffler, then the muffler shop just fabricated the rest... easy job really... sounds great now... A little quiet for my taste but the sound quality is nice...

Dustin98SS, that's not what I'm talking about...I wish it was that easy, but the searches I've done say that any bullet style muffler in place of the resonator will not be much quieter. It seems the only way to go is with a large style muffler. My wife is driving the car most of the time and hates the noise.

I have an idle video in my sig... keep in mind my mods... and I don't have any cats... so if your wife's car is somewhat stock then it would be much quieter...

Well I see you have longtubes so dont go with a bullet style muffler. It will sound terrible. That is my old setup for sale by the guy that built my true duals. I think magnaflow makes a round chambered muffler that might work. Check their site out.
Another alternative is to put true duals on the car and buy your wife a Corolla

Update...went with the Magnaflow #12267 from Jegs and the Corsa clone tips from http://www.chromeandperformance.com/corsatips.html
We cut it over the axle where it splits into two pipes and fabbed 3" into it and the 2.5" tailpipes. Absolutely quiet compared to what it was. I'm very happy with the deep tone and it sounds perfect when you wind it up. Before, just a modest run from a redlight would attract too much attention...now I find myself not even thinking about it. I also had him weld in a bung for my wideband.
