!!Doug Thorley Headers 4.7L V8!!

[jcaino]

Are there any options that delete the cats and bolt up to stock exhaust? Long tubes? Or something a competent exhaust shop could work with. I dont need to worry about e-tests

Yes, that is exactly what the long tubes are.

Same situation here. They offered me another set of the revised version which includes stainless SAIS pipes for $800. Got a quote from the only shop I can find to touch them for around $3500. Their lifetime warranty means life of the headers. In my case that was about 35k miles. lol The *tick tick tick* is now a *blap blap blap*. It sounds like total shit and the entire cabin smells like exhaust at stop lights.

Does anyone know if the 03-04 headers work on an 05-09 w/ SAI delete? Wondering if I can avoid the whole SAIS pipe issue by deleting and installing block offs. Also wonder if moving O2 sensors to before/after the y-pipe cats will be sufficient to pass the OR DEQ sniff test.

I'd be interested. '03 SR5

Yep, same for me, with a “we’ll make some in a few months, but can’t say exactly when”. Last Doug Thorley product I’ll buy, that’s for sure.

Update:

All headers should be shipping today. Doug Thorley also had a price increase today august 1st, BUT, BUT I haven't changed the price on the website yet, so you'll still save a little off what they should be.
