My GMMG and QTPs
I didn' t have to grind my old standard QTPs, BUT, I had to with the new HVMCs. I had to grind below the #2 primary tube, on top of the K-member, but, oh well. It doesn' t hurt anything, and maybe my motor mounts are starting to sag a bit. But, it does not seem to be a common problem. Each car is a little different. That' s how GM makes them...
I had to grind the K member a little and a little square part on the block with a Dremel and a stone

Now I need a second pair of hands to help me hold the headers while I put the bolts in or the other way around
Today I started working on the Driver side header and after much playing around I got a Dremel out and grinded the K member a little and a little block of metal on the side of the block to make it fit.
I will start putting on the Y pipe and tighten everything down and off I go for a quick testing
I have QTPs with the QTP catted Y and the I pipe on the GMMG is too long....
Im just trying to get some input......

I have a problem with the driver side cat. Its way too low and it hits on everything

It looks like the problem is at the Y merge collector, It seems like the tubing that goes to the driver side is pointing down too much.....
I really dont know what to do....... I cant drive it like this, it even hits when im on the freeway and there is like little coasters or bumps.....
Can you guys please post pictures of the catted Y or the exaust so I can get an idea of what to do ????
Thanks!
Another big problem, The driver side header hits on the steering shaft, What can I do about this ?????
Thanks for any help!
The splined shaft on the rack has a slot for the bolt to keep it from sliding off, so it has to go in THAT spot.
Another idea is to, brace yourself, put a dent in the primary tube.
