    Dynomax over SLP

    I have a Loudmouth on my car currently. I am putting LT's on in the next few weeks. I think that with the LT's my exhaust will be too loud and too raspy. Can I just take the Loudmouth resonator out and drop something like a Dynomax bullet in its place or is there a better muffler to put in. I like loud and throaty. I love the sound of my loudmouth but i could do without some of the drone. need advice

    i got a lm2 bullet muffler for the same reason but havent installed it yet. i love the volume and tone of the lm1 at idle but hate the rasp.

    Dynomax sounds much better than the SLP's IMO. Especially on a cammed car. I ran long tubes into a ypipe then directly into the bullit then dumped. Sounded great for the price.

    I don't have any experience with the LM1 system, but when I bought my car, it had the LM2 system on it. Drone was awful and I'm completely stock. I replaced the resonator with a Magnaflow bullet muffler. It was deeper, but still too loud for me. I ended up replacing the entire system with a Magnaflow catback. Much more quiet now, but I love it. I've heard this system really wakes up when you add long tubes too.

    I have an lt1 with the LM2 system with long tubes and ORY. Egines are not the same but mine has rasp at a certian rpm all the time and I have been thinking of using a dynomax bullet, borla bullet or magnaflow bullet as well but from what I read it wont change it that much it is just going to be loud, raspy and have drone. I have not seen anyone use 2 in a row though. This was another thing I was thinking about tring.

    Here it is before with the I-pipe and axle pipe still on. Don't have any of it dumped right after the y-pipe. Sorry bout the cell phone video.

    Here it was with an SLP resonater in it's place. Had a horrifying rasp between 2,700 and 3,000 rpm with this set up.

    did the dynomax cut down the sound level and raspiness of your car?

    Rasp was completely gone, sound level was quieter but it made it a lot deeper and full sounding.
