slp?

The SLP Dual Dual and the LM series are some of the best flowing catbacks out there.

flowmaster sucks doney balls, I'd rather have a stock catback.

2OTL > dual dual

Ugh...2OTL...

I hate the look of that.

[GOR1LA]

DID I MISS THE SLP LM'S?? or were they mixed in there? Pretty sure they are one of the loudest!! and maybe up there on performance as well...Those graphs FAIL lol...good find though to bad they didn't do more mufflers.

I have a 40 series flowmaster on my Trans Am. And it sounds bad ass.
But I'm not pushing a whole lot of HP.

I like the flowmaster sound.

When I change motors, maybe ill look into a different muffler.

a loud mouth falls in the catagory of no mufflers cause it isnt one.

true duals flow/sound the best

flow masters have a good flowing muffler the signle chambers check out smokeyrider05's car

i pick a muffler for sound instead of flow,i ran no muffler all last year tho

I have a flowmaster 80 and hate it. It doesn't flow, its quiet, and sounds like all the hillbilly trucks that run around here. I don't know what I'm going to do, but I gotta do something before the M&G

Magna over Flowmaster when you had the 3.4?

Flowmasters on 3.4s sound alot better than magnaflows do.. but to each their own I guess I am just biased haha.. well.. on FTV6 alot of V6 guys prefer flowmasters


Yea Joel is should sound good.. There was a guy on camaroz28 I think? That has the setup that you want to run and it sounded mean as !@#$

I would disagree with your ftv6 statement, most people know blomasters suck and don't recommend them to people with v6's

we are talking about flow, however that is why i got rid of mine.

Yeah, SLP systems are really, really low-restriction.

For that matter, my Camaro's muffler (a Flo-Pro) was rather loud, too. I liked it.

The first Camaro I looked at was a '95 Z28, with BBK headers and a Flowmaster catback - God did it sound Orgasmic. It was loud, and just sounded wicked.

I loved the Magnaflow on my v6. It gave it a really nice rumble at idle and steady acceleration - as long as you didn't get too close to redline. I also liked it a lot more when I had a cat then how it sounded after the cat was removed.

I have a cammed 2000 SS with ARH long tubes ORY going through a factory SLP dual-dual, putting out 390 RWHP. Only 5 HP diff between Cutout open and closed, It's a great flowing muffler. Wish they had tested it.
