Cat and muffler options on a '99 Suburban (K2500, 4WD with the 7.4

[oifla]

Hello all,

I have a stock 1999 Suburban (K2500, 4WD with the 7.4L/454 engine).

The truck needs one of the catalytic converters replaced and I figured that while I'm into one, I might as well replace the other and update the muffler.

ANy recommendations on catalytic/piping/muffler combinations?

I'm would like to open the exhaust up a bit as the stock muffler seems very restrictive but I'm not seeing a whole lot of info on what is available. I think I'm going to go 2.5" catalytics and 3" piping and muffler after that but I am posting/asking because I am not set on that. Would appreciate any thoughts / experiences with cats/exhaust set-ups on the 7.4L

Thanks!

How are vehicle inspections performed in your area? If they require hooking a computer and checking for MIL, you will be best off buying a good quality converter. It will last you longer.

 

If they only require a visual, about any converter should be fine, just do some research first. Some replacements have been prone to blowing out, which could clog up a muffler.

 

As far as muffler, youtube is a great source to find a muffler you like the sound of.

I'm in a small town in Indiana so there are no inspections to speak of. I'll do the rounds on youtube, thanks!
