Straight pipe vs. SLP LM vs. Flowmaster axel backs

[BOSS4.6L]

Does any body live around Pheonix AZ that has an SLP Loudmouth exhaust or the New flowmaster axel back exhaust kit installed on their 05 GT? I am haveing a hard time deciding which exhaust kit to get so I was hoping that some one around the Pheonix area would have one of these exhaust kits and maybe we could meet somewhere so I could take a listen. I cant make a choice just by listening to sould clips. :damnit:

I would also like to here about the B&B axel back system or any other system out there. Also has any body just taken off the factory mufflers and started the car up to see how it sounds with just straight pipes.

I heard is sounds bad with the mufflers off. SLP Loudmouths for me.

Unfortunately I cannot speak from experience (waiting for 05 stang). But I plan on getting the SLP loudmouth for mine. From what I can gather from their website the loudnouth kit is a straight pipe. There is no mufflers with the kit, they replace the factory mufflers with straight pipe, which gives it such an awesome sound.

Okay, guys: I'm struggling here. If you remove the factory mufflers, do you just drive around without them or add new ones? Sorry to be so clueless...

An axle-back (as well as a cat-back) is going to replace your factory mufflers. That's pretty much all it is, mufflers and tips (axle-back) or mufflers, tips, and some pipeage before the mid-pipe (x,h,y,etc). If you just "removed" the mufflers, the tips would come with 'em and you wouldn't be able to see any pipe coming out from under the car anymore. I'm sure it would also be loud and very un-street-legal. These SLP Loudmouths they're talking about basically replace the factory mufflers with some really...straight through looking ones, followed by some new tips.

Hope this helps, I've got very limited knowledge myself. I'm just learning as I go .

p.s. - Also, there are some axle or cat-back systems out there that do totally eliminate mufflers, but you're still going to be replacing that part with some pipes and new tips.

I'm still waiting on my Flowmaster Thunder Back Kit from LM Performance. Been two weeks now and they still are waiting for it to come in to send to me.

Why doesn't anyone seem to like JBA?

My SLP LM is comin in the mail...loud and proud!

I have taken off the stock mufflers to get an idea of how loud the SLPs might be. It didn't sound nearly as good as those clips do. It was loud, but not insanely loud like I thought it would be.

The SLP loudmouth axle-back kit is straight pipes - but BIG pipes (no muffler whatsoever). To the best of my knowledge, it is street legal (most regulations have to do with emissions not sound levels). I plan to get them.

Hey BOSS,

Im in AZ, mufflerer's removed.

Did it at Scottsdale Muffler. We just put straight pipe back on, and nice chrome tips. Give me a call if you want to check it out. I can get you a great deal on it from them as well.

I (and everyone else so far) think it sounds bad ass.

Yo CASP3R, do you live on the East or West side of Pheonix?

 

[bleedingvayneAD]

What is the best price people have found for the SLP?

 

[sacrstang]

I bought mine for $224 from lmperformance. The other prices I saw were in the ranges of $249-$265.

Do you have to do a tune up (predator etc.) when installing an axleback exhaust? I want the sound but dont want to pony up 400$ right now for the tuner.....will I notice any performance difference with the axleback? Thanks.

 

[Roni]

If I was only twenty years younger I would get some of those loudmouths, But I have to use this Car for work so I better stick to the stock system, Which sound excellent as well.

No you don't need to do a tune, and you probably won't notice any horsepower increase with axlebacks. It's mostly for sound.

East side, valvista and broadway. If thats not close to you, we could meet up somewhere.

I live on the West side, Bell and Reems rd. I am not sure exactly where Valvista and broadway is though. I am not that familiar with the west side.

 

[CASP3R]

to get to east mesa you take the I10 east to the 60 east.

From where you are, you may take the I17 south to the 10 then the 60.

 

[BOSS4.6L]

I will have to check out a map and see about a good meeting place that we both can get to. If you know any good places let me know. oh and by the way my name is Jeff.
