On what truck bro??? Triton ??

It is always the cat restricting all the true power of a turbo-diesel....
Where did you do the decatting? Workmanship ok bro?
Triton 2.5 A/T. Got it done at the exhaust workshop nearby my office in Subang Bestari. RM 350 to replace down pipe behind turbo till cat box. I also opt for additional RM 150 to replace the pipe after the cat with full stainless steel. Workmanship is superb.
The clogged cat box.
The heat shields, will be using some back.
Stock down pipe and cat box removed.
Prepping the stainless steel pipes.
Almost done, just need to weld the down pipe. Stock pipe after cat is 2" only. I replaced with 2.5" from turbo to all the way back. Good enough for A/T.
This is a complete replacement, over 3' in length. Minimize the joins. Cost is around RM 500.
TIG welding in progress.
Next project is full stainless steel I/C pipes.
