I know I've asked a lot of exhaust questions on here but I got one more...what is the loudness difference between these two mufflers/pipes? Thanks again!! And I have a catted x-pipe btw.

Lm1 will be louder. Magnapacks will sound 100x better.

When I had my 2valve, I had magnapacks and a catted H from MRT. I liked them a lot. Really quality. However, I'd probably go SLP if it wasn't my daily driver.

I got a set of pypes M80 race mufflers installed on my 2004 Mustang GT. Budget loud mouth mufflers. They sound mean.

You won't be disappointed with SLP's. Especially If you are looking for loud.

Only thing that turned me off from the SLP loud mouth mufflers was the price. I got both my m80 for less than $90 new from American Muscle.

Lol. Yeah, I've got a pretty good amount in exhaust. Not as much as some tho. My neighbor does say it's the best sounding car he's ever heard in his life tho. It's loud and nasty. MRT off road H with SLP loudmouths. Only been pulled over once for being "too loud".

I need to get a video posted up. Lol. I try not to start it early, if I don't have to. Some mornings it's behind my truck so I have to. Nothing like it before 5 am.

slp loudmouth compared to magnapacks?

Yep, I went to a show with a friend, his car literally made my car sound like a Prius. My ears were ringing all the way to the show. And what's really bad is we made the car that loud, longtubes with an X pipe, side exhaust. And it was just as loud at an idle. His car was like, wake the frigging dinosaurs loud.

Bahahaha! I wanted something like my 97 cobra sounded. It was full MagnaFlow. It sounded amazing. I went just a wee bit louder.
