Default Anybody have SLP high flow cats?

Just got slp lm'2s on 04 GT. Not as loud as I wanted. What would be my best option, high flow cats, x pipe, or h pipe.
Thanks

Do you want it loud or deep? If you want it loud get X if you want it nice sounding and deep get the h pipe.

If you want a loud exhaust system I would recommend getting rid of the LOUD MOUTH II's and installing the original LOUD MOUTH system on your car.

I have an '02 GT with the entire SLP 330 HP Performance Pac (330 Flywheel HP)
The system includes the following:

* Long-Tube Headers (ceramic coated with 1 5/8 inch primaries)
* PowerFlo-X Crossover Pipes (Short Assembly)
* High-Flow Catalytic Converters
* Loud Mouth Exhaust System
* 3.5 inch exhaust tips
* DiabloSport Predator (SLP Tune)
* Underdrive Pulleys (SLP)
* 160 Degree Thermostat
* K & N Air Filter

* The exhaust system components are stainless steel and fit extremely well.
* The Catalytic Converters can be swapped for Race Pipes (simple swap).

My car is loud and has a very aggressive sound especially at wide open throttle. I am very satisfied with the performance gains as well as the sound. When it came to an exhaust system for my car I shopped around and listened to the way the other exhaust systems sounded. I decided to go with SLP and couldn't be happier.

If you want loud I recommend this setup.

The SLP components are not cheap by any means but they are well worth the price.
I had the complete exhaust system (including headers) installed by a speed shop for around $600.

The only other mods to date that I have on my '02 GT are Ford Motorsport 3.73 gears and Ford Motorsport Slotted and Cross-Drilled Rotors.

If you want to hear what the complete system sounds like you can check out the sound clips that SLP has for its LOUD MOUTH system at www.slponline.com

If you have any questions feel free to e-mail me

Loudmouth 1's + Offroad X-pipe will make people cry as you pass them by.

Will drone out powerstroke deisels.

My friends keep talking about how I won't be able to hear my radio, which I could care less.... And I just keep telling them, they won't be able to hear THEIR radio if Im in 30 feet of them, LOL!

(Look at my sig [8D] - Going in next weekend)

I dont get this whole X-pipe equals loud and H-pipe equals nice rumble. My Brothers X-pipe rumbles and sounds better than my H-pipe, hands down.

It's all an opinion thing! Just gotta look around and do the best research you can as to how each setup sounds and pick what you like best. mustangexhaust.com has a ton of stuff on it.


I have flowmaster... i love them except they are too quiet on WOT (although I have never heard it outside at WOT)
