Sup. I'm try to find out is there any HP difference between the SLP cat-back and the Flowmaster cat-back. I'm already running the Flowmaster set up, but I'm looking for a bigger sound and performance. Is there another set up out there you guys know of that can give me both or should I stick with what I have?

 

I personally like the sound you get from flows as opposed to SLP's and from what I hear, the power output you get from SLP is nothing special. Here's a short clip of my 69 & 03. The 03 has full stainless steel bassani ...

 

You might get a couple more notch's in the hp catigory but honestly nothing you will probably feel. If you like the sound you have on the car now leave it. Find hp somewhere else in the car.

 

+ fucking 1

And like Dave (91notch) said find the Hp your looking for somewhere else.

Like what kind of Mid pipe are you running Stock? If aftermarket, Is it an H or X?

Here is a clip of my car.

This clip was taken on a Monday at 11am I'm running 1 5/8 headers 2 1/2 off road H-pipe flows with turndowns


This clip was the same day only thing i changed was I went to an X pipe that was it. Car felt like it was so much smoother in the rpm range and it was a little quieter at idle and cruise mode. But it gave it kind of a raspy sound when i stepped on the pedal, which i like cause i thought i sounded different.

 

That sounds good dawg!
