Cap off air tubes
Just got these pacesetter LT's. What size caps to plug these?

I think they're a 3/4 pipe thread.

Re: Cap off air tubes
Looks more like a flare fitting, using a flare cap:



An NPT thread would be tapered.

Hmm, you're probably right. I didn't see the flare on there and assumed it was the same as my headers.

If nothing else any competent exhaust shop can cut those off and weld them shut in about 2 minutes. Just spray some high temp paint over the weld.
