It might shake , but it shouldnt rattle and roll .
Should come turbine smooth at around 2.0000 rpm . Give or take a zero or two .
Ex Haust knuts - you need the proper tool ( Make One . ) and LEAN on it , When the injuns HOT .
After about four efforts ( seperate heat cycles ) the widdle copper washers are flattened , and if the pipes are aligned ,
itll stay tight .
If theyre Not Aligned , itll likely tear the stud thingos in the mufflers out .
If the Iso's are over 5 thou . , itll roll & weave .At Speed . 2 1/2 is as tight as Id run em . To 4 1/2 .
If the mounts are straight & alls square . Otherwise any binding transmitts the shakes .
There should be NO BINDING in the mechanism .
Keep it below 90 in third gear . Tho 23 T will give 112 odd .
