Well I guess I didn't read carefully enough, so Doc Olds below is a link to the GM accessory part this one is the touring model for alpha's there is one called a performance model for the non alpha 19154703 and touring 17802015
Cat-Back Touring Exhaust System 19165601 - Crate Engine Depot
And Tainter I guess since all H3's already have a cold air intake by design the only gain would be a smoother intake tube. I doubt that trying to suck air through a fender channel is considered an optimum design. I let you know about the ported and polished TB mine is on the way. The dealership where I get my H3 serviced said I needed mine cleaned but wanted 185.00 to do it. got home and looked for myself I wouldn't eat off it but it was not that bad nothing a little TB cleaner and toothbrush didn't fix.

Thanks for the online bashing I kinda wondered why there are very little NEW posts here you guys run everybody off that asks a question. And at least one of you don't have a clue

 

SKU # 19165601 used to be for the H3 Alpha without Under Body Protection, and has welded tips. Was actually made by BB with H3 Logos in the tips, offered March 2008, no longer available. However, you may find one in stock with somebody somewhere. I was just letting you know there are none made now, guess I could have been clearer?

If you do a search through the GM Accessory supply houses you will find no listings for it. I would link a few for you, but they don't work because of the drill down needed to get there.

Now if you were to find one in stock and drop the overpriced coin on it, I would be impressed and, more importantly, you could tell us what you think about the system. I've seen lots of Alphas w/ cat back systems, just never a GM version.

 

There are 26 part # 19165601 floating around at various dealers across the nation, and there still shows stock available at the "vendor".

However doc's right, retail on them is $1200, you might get one at whole sale around $1020. But still, way over priced.
