Here is a picture of my exhaust going through the center cross member on my 69 Suburban.

BCOWANWHEELS · 03-19-2017, 12:07 AM

WHAT size holes did you cut and did yoy plate the crossmember . I,am gonna run 2 1/4 pipes

rocknss · 03-20-2017, 12:07 AM

I had an exhaust shop build my exhaust. I'm running a 2.5" exhaust so I believe the holes are around 3" in diameter. The X-member is not strengthened where the holes are cut.

Sorry to hijack your thread but what sway bar are you using here in this ?

BCOWANWHEELS · 03-20-2017, 01:33 AM

stock sway barbut I have a adjustable one ready to go in

Here's a couple of pics of my cross member through holes. I used 4 1/2" tube by 1 1/2" wide and 3/16" thick. I picked up the tube from a fab shop down the road from me.

BCOWANWHEELS · 03-20-2017, 04:46 PM

super rudy thanks. did you also flip the truck arm mounts

**RodnRudy** · 03-20-2017, 05:00 PM

Yes I did flip the truck arm mounts but I changed them back because I thought there was too much pinion angle when I got the suspension loaded to ride height.

BCOWANWHEELS · 03-20-2017, 10:41 PM

RUDY, how much did you drop the rear suspension. mine is 6-7 lowered lwb and is hard on carrier bearings

tsetsaf · 03-20-2017, 11:34 PM

These look great. We have an LS and that exhaust gets really hot... we also have air ride with nylon lines. Real hot + nylon lines = sudden leaks. If your plans include anything plastic/ melty in the area consider heat wrap or insulation/ heat shields.

BCOWANWHEELS · 03-21-2017, 01:27 AM

no plastic on my truck

**RodnRudy** · 03-21-2017, 06:55 AM

My 68 has a 5 1/2-7" drop but I have a one piece drive shaft.

BCOWANWHEELS · 03-21-2017, 07:14 AM

rudy, is your truck lwb

**RodnRudy** · 03-21-2017, 07:27 AM
