Which one sound better slp loudmouth or magnaflow? Which one has the better flow Or louder. Ls1 98. Thanks

loudmouth would be louder but magnaflow sounds better. And any hp loss between the 2 is negligible if it even exists

I like magnaflow but I already bought the the slp. And I'm gonna put two mufflers I think it's goin to b loud. What do u think I should do two or jst a single muffler? I do not want it very loud cuz I can get a ticket for that

Bought it between 11 minutes of starting the thread?

Reading your other threads you should be fine it's when people add headers that it gets to loud and raspy, if you keep your car smog legal I think you should be happy with just the single resonator it comes with.

loudmouth 1 or 2?

I had the slp already bt I wantd to buy the magnaflow. It's slp 1

Magnaflow.

By a ton.

depends, if your not adding headers then my vote is for SLP but if your taking the cats off and adding headers and already have the SLP exhaust just get the magnaflow bullet muffler which is a direct replacement for the SLP resonator, all you have to do is cut i believe 3/4'' off each end of the magnaflow and it will kill the ddrone and rasp youll get with the resonator

have you done this? im in the process of removing a wrung off header bolt so i can finish up with the header swap. i went with the BBK longtubes.

**basballny2** · 02-28-2010, 10:10 PM

yup, as of right now i only have a sound clip on my phone but the next time i go start the car ill take a clip with the camera if your interested in the sound

its up to you, but most of the time mic's and speakers dont do the exhaust justice.

I did this same thing with pretty much no change to the exhaust drone. The note was deeper with the magnaflow bullet, but was unbearable on the highway.

I ended up getting the full magnaflow catback. Much, much happier with this setup.

stock for stock the Loudmouth is alot better than the Magnaflow.. true, once you add longtubes + ory the LM does not sound that great. but magnaflow is very quiet.

**98maro** · 03-02-2010, 12:04 AM

I'm gonna get the longtube. No cats and a single slp 1 muffler will that sound loud and good?

it will be very loud and raspy if you do Longtubes/ORY/LM1.. it might be very unbearable if you have never rode in a loud car. i actually loved it..especailly going WOT!!!!!!!! i have magnaflow now, and yeah its quieter and more pleaseant but very quiet..

**tpilews** · 03-02-2010, 06:56 AM

**Spaz** · 03-02-2010, 08:50 AM

Still plenty loud...since it seems like a lot of the younger crowd prefers something obnoxious.

I feel old....that may actually be louder than my car with duals and a pair of Magnaflow mufflers.

My car sounds similar to that to me, but with a deeper tone.

Yeah, I went a picked up my car about 1.5 hrs away from me. The loudness of the exhaust actually gave me a headache on the drive home (all highway).
