Qa1 Rear suspension and exhaust...
I know there are more than a few people here running the QA1 rear suspension set-up. Just curious as to what you guys are doing for an exhaust....I'm not quite sure how to get out the back with the exhaust with how bulky the panhard brace/bracket is on the driver side. It looks like it would make the exhaust/tailpipes hang real low to get under it (I also have a rear mounted tank).
If anyone has any insights or pictures, that would be super helpful. |

Re: Qa1 Rear suspension and exhaust...
I have an LS3, 4L70, full QA1suspension on a 2 Wheel Drive 1972 Blazer. I also am not happy with the way the exhaust is on the driver side. I also do not have pictures of the driver side and my Blazer is over an hour away at the body shop. They make mufflers that have duel inlet into outlet for Camaros in similar cars. I may look into installing one of those as far forward as I can and then running the exhaust on the outside of the frame rail to the back. But I’m not 100% sure that it’s possible yet.

This is not mine, but this is a pretty trick set-up if you are looking to go out the side.

Not QA1, but here's how my exhaust was done with my TCI suspension.

Good luck with your exhaust. And being a blazer I had to bring it out the back as it could not be dumped in front of the axle or fumes would definitely get into the passenger compartment. |

So for anyone asking this same question in the future-it does not appear that with QA1s pan hard bar design (which includes a 2nd bar that acts as a brace) allows for easy routing of the exhaust over the rearend. As Thealien did on the driver side (over rearend then under the pan hard bar), I did as well on both sides. Exhaust hangs lower then I would like in that spot, but sway bar is just as low and shocks are still lower.
I took off the shocks and jacked the rear end up to the bump stops to ensure everything cleared, and realized that even on the passenger side the exhaust needs to hang low and go over the rearend then under the pan hard bar. Thealien, just an FYI but if your running it your way on the passenger side (looks like between the panhard bar and panhard bar brace), and the panhard brace is on the top adjustment on that same side, it will start crushing the pipe (assuming it’s 2.5) when the suspension is fully collapsed on the bump stops. It won’t be a problem if it’s not adjusted to the lower/lowest settings. This is what I ended up with- |

Thanks for the pictures and the update. Would love to see a few more angles if you get a chance. From underneath how it goes under the bars etc. |
