Need exhaust advice

**Yellow_Bird** · 06-10-2007, 07:07 PM

I'm going to put a new exhaust on my car. I cant decide between Flowmaster's(80 series) or SLP's(loud moth II)????

Thanks

!!!!UPDATE!!!!: Ok Guys, I'm going with the LM II, but I have another Question. If I buy the "Loudmouth II" Bullet Muffler and Tips, could my local muffler shop make/bend the rest of the system???

P.S. the guy at my muffler shop is great, very good at what he does

Thanks

Flowmasters suck. Go with the LM.

**Yellow_Bird** · 06-10-2007, 07:38 PM

Well I have them in my LT1 and i love the sound

Choosing between the two that you offered. Definitely go with the LM.

Ok Thanks

Flowmaster is just junk as far as flow. If you realy like the sound, then just go with that. But if you want sound and performance, LM is the way to go.

New era performance parts has them. I just bought one for my car. $377.00 shipped

i used to have flows on my 2001 trans am, it sounded out but didnt really do much on performance. Then i slapped on SLP loudmouth 2. the sound is great and you can feel a little more get up when you take off. But it sounds really good and its only about 432.00 on summit racing but its going for i think 330.00 on ws6 store correct me if im wrong. but thats what i have on mine i changed my muffler to the loudmouth 1 because its louder, but then again its all up to you.

I like my flowsound, but I have not idea on performance, supposed to be just like a 40 series except it actually comes in a cross flow and is cheaper.

The blowmaster is probably a 2-4 HP gain over stock. By far the worst of the catbacks when it comes to performance gains.

Flowmaster may suck flowing on a LS1 but they sound sweet.

Trust me. It sounds way better on LT1s than an LS1. If your never gonna put long tube headers/ory on your LS1 than I'd go with the Loudmouth. Headers/ory will make it just too loud and obnoxious. Loudmouth sounds hot with the stock manifolds and cats.
