NPP Tips
I had Corsa's on my '05 C6. I've seen the tips on the standard exhaust on the 2008 and was very disappointed. I'd decided I would have to replace the tips or work very hard polishing the tips to make them nearly as nice as the Corsa's.
Car and Driver's article mentions a different tip on the NPP exhaust and the pics look really nice, I've ordered the NPP. Does anyone have any pics of these tips? Do you know if they are polished SS?
Thanks

I am quite sure they are polished SS. I polished them pretty good the weekend I got the car home (I have to polish my wheels on a regular basis). They seem to come out pretty good to me. I'd say they look as good as the B&B's have had before.

I bought this kit from Pipedreams here on the forum.

I have stock tips. Mine didn't turn out quite as good as Corsas... yet. But close. I worked on them for about 1/2 hour last weekend and made a lot of progress, nearly perfect but not 100% yet. I'll give it another go this weekend. The kit includes the stainless rouge and buff wheel. Kind of pricey but it is doing a good job.

If I get a '08 or '09, I am going to take my '07 Corsa's off and put them
on the new car and not bother with the NPP option. No offense to any, but I dont like the look of the being able to see those butterfly valves in the pics and also seen first hand at the dealer. Not to mention, I am sure the Corsa Sports add 6 horses too, now that the NPP claims 6hp. I will say while I love my Corsa's, I dont like the CORSA lettering on my tips either.

Is the NPP option similar to the A&A mod that was popular on the C5??? Of course only with the valves?? I ask because I did the A&A mod on my 99 for about $70 dollars back in 2001. http://www.teamterrier.com/Mike/Exhaust/Exhaust.html
It inserts a by-pass tube and gets exhaust before it enters the muffler (on one tip per side). Many claim it was one of the best and cheapest exhaust mods ever? Could this be were GM got its idea from??? I liked it.

In the case of the NPP exhaust the by-pass actually takes place inside the muffler housing. the valve is at the base of the tip and the backpressure forces the exhaust gas out the side of the inner most pipe, around a channel and out the outter most tip.

It would be nice to get a C5 with Andy's exhaust mod side by side with a a NPP C6. Of course with Andy's mod the exhaust wasn't changable (it was always open).
Thanks for the info.

What to use?
I have found two really good products for aluminum and stainless steel. I use Mother metal polish or even better semi-chrome. You won't be able to find semi-chrome at an auto supply store but at a motorcycle shop. This product has been around for 35 years, how long have I been riding Harleys, and is great. With a little work, aluminum or SS will look like chrome.

The NPP exhaust for 2008 will fit non-NPP cars from 2005-2008. The NPP (or Z06 bi-mode exhaust) for 2009 will only fit on 2009 and 2010 cars.
