    Poor man's Borla catback

    Has anyone on here put a small pipe (3/8") that bridges the axle over pipe (muffler inlet) to the passenger side muffler outlet pipe on a LS1 F-body??? If so, how does it sound. Does this increase performance or does it provide too little backpressure and decrease low end torque. Is there excessive exhaust drone on the highway? Would it perform similar to magnaflow and borla catbacks?

    I remember reading about this on the old LS1.com site, but couldn't find any info on this setup.

    Thanks,
    Jim

    No one has done this?? I was thinking of using a 1.25" bridge pipe between the muffler in pipe and the pass. side muffler out pipe. Will I still have good low end torque?

    Thanks,
    Jim

    depending on what catback you have on there you probly wont be able too feel a difference. I would think this would be more of a sound mod than performance.

    My '00 Z28 has a stock exhaust (stock catback). I like the sound of the stock setup, although it is a little quiet. The only reason I'd do this is for performance. The stock catback seems restrictive, so I would think this mod might help. Would I see better power gains with a regular Borla or Maganflow?

    Thanks,
    Jim

    Replacing the stock catback will let your motor breath a lil better so yea i would replace it. You will also get a better sound out of it. Personaly i wouldnt pay 700 for a catback but thats your call. Check out ls1sounds.com for sound clips. I like the magnaflow, just stay away from flowmaster.
    If your gonna keep your catback then adding a cutout is allways an option.

    I drilled the holes for the poor man's borla using a 1 1/8 holesaw, but I never got around to putting the small pipes on it yet. I LOVE the sound of it, but don't expect any performance gains, I only did it to make the car a little louder. It is very raspy for about the first 2-3 minutes after start up (not sure why) but after that no rasp whatsoever. Give it a try, if you don't like it you can always cover the hole.

    a cutout on the stock exhaust will give you a hell of a performance increase.

    Yes, I did that several years ago before installing a custom catback. I used two 1" copper street elbows for the muffler bypass pipe. A few weeks later I did a second one a few inches away. Testing showed an average of 7 rwhp increase with the two bypass pipes done. It will not yield you as much hp increase as a Borla, but considering that the parts cost about $10, it wasn't too bad. The sound was somewhat louder, but not real raspy.

    If you are on a tight budget, it's a good little mod. But if you've got plenty of money, get a real catback.

    Catbacks give you more HP not only because of the muffler, but because of the I-pipe itself. It's 3" instead of 2.75" and mandrel bent so it won't crimp down to 2" when it turns.
