Will dual exhaust off a 73 thru 77 Suburban fit under a 90 Suburban ? I want headers on Avaburb and if I do it myself I can do away with the catalyic con. LMC has duals from monifolds back with turbos for a 73-77 for $220 .Gil.

What I was trying to get at is the Catalytic Converter the only difference . Didn't they start butting them on in 78 , so in catalogs they don't show early exhaust fitting newer trucks ? You know , kind of like why a muffler shop can't put duals on without the converter without getting in trouble with the law . I wouldn't think the frames would be to different , anybody know about the frames ?

As long as you arent putting any big chrome tips on the end of the exhaust pipes you should be able to get it for the same price or less from a custom exhaust shop. My true dual on my 99 cost me 380 and 90 of that was for the big chrome tips I put on from Magnaflow. So you should ne able to get a custom exhaust, and EXACTLY what YOU want for under $300.99 K1500 Suburban LT "THE BEAST"

If there was no cats on it from the factory they cant make you put them on, it would really serve no purpose, the cats are there to help burn up the crap that comes out of the exhaust and without having the O2 sensors to pick it up they cant do their job.

The muffler shop I use will do what ever you want to pay them to do. I've had cats cut off in the past and they asked if I wanted to on my current truck and I said no. Did you ask them?
You can always have them do the exhaust and then go back and put a test pipe in.06 GMC Sierra CC 4x4 4.8
