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.

I had to make a custom bracket that slipped into the hanger on the passenger side. In the picture it wasn't in yet.

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

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.

I just received mine and the muffler shop I went to couldn't do it because it's stainless steel and they said something about cracking.

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.

No welding? The guy at the muffler shop was talking about how he can't weld a hanger because it's stainless steel.

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.
