SLP Loudmouth copy
Has anyone ever used a phab catback. It is just like a loudmouth, being stainless and having a bullet style muffler, but it is about $200 cheaper.

Re: SLP Loudmouth copy
It looks to be identical in routing to the loud mouth... Only difference I see is the missing SLP stamp on the muffler. I'm sure its loud as hell.

Re: SLP Loudmouth copy
So I ended up making a video. It sounds a lot more raspy in the video than it is becuase it is in my barn. It was snowing and I didn't want to get the car out. I will make a take off video some time this week. I don't have much time to make a video becuase of school, but we are on break, so I will make one probably Wednesday or Friday.

I have the dynomax equivalent on my LS1 swap with custom Y, no cats and it is so loud I get the finger, scare pedestrians etc... However, I get lots of thumbs up too.

Re: SLP Loudmouth copy
Love the sound!! Mine has a Dynomax, but it is Way Way more quiet. Are you running headers and is it stil a 5.0L?

Re: SLP Loudmouth copy
Did you have to do anything to the computer? I'm looking for a deeper sound, but I don't want to open a can of worms by changing from stock if I can avoid it. My 1985 has the 5.0L TPI
THANKS

Re: SLP Loudmouth copy
HOLY HOOKER HEADERS BATMAN!!! They make more styles than Kardashians have Twitter followers! Do you happen to know what style fits our cars? Do your headers turn back, I think they are called "LONG TUBE" or are yours short and dump straight down? Pictures of your exhaust would be great!!

Re: SLP Loudmouth copy
IIRC the I pipe was close to 2 3/4 and when it split up into the two pipes they were 2 1/2. The only reason I did the Exhaust was because of the sound, so I really didn't care about the size.

Re: SLP Loudmouth copy
I had to make a passenger side hanger for mine. Plus the kit that I bought came with clamps. The hanger that I made is just a piece of metal bent into an L shape, and slide into the top of the hanger. I then drilled two holes into the metal and ran a bolt and nut into the piece.

Re: SLP Loudmouth copy
If you want pictures of the hanger, I will get them for you when my car gets out of the shop. It will probably be sometime next week.

Re: SLP Loudmouth copy
So i took it to another shop who do custom work and they welded everything. It gave me a deep sound not sure if your sound changed over time? Heard that exhaust need to break in. I have a 305tpi with no cats like yourself, but no headers.

Re: SLP Loudmouth copy
I got my exhuast on in December and parked my car in January, so I haven't had much time running it.

Re: SLP Loudmouth copy
The car is getting new injectors sometime this week. Haven't been driving the car very often. I'll get a sound clip after I get them installed.

Re: SLP Loudmouth copy
Got a new clip as requested. It only is from the outside of the car. Haven't got the one on the inside yet
