Pics of X-pipe install - ZR-1 Net Registry Forums

Nacho_ZR1 · 12-24-2010

So now that I've gotten a baseline dyno of my car and am pretty happy with the results, it's time to start Round 1 of my performance mods: Haibeck chip and x-pipe install. Took the car to a local muffler shop in Dallas. While the car was on the lift, I snapped some photos on my BlackBerry. I have a stock exhaust, by the way, with Dynomax mufflers.

Here's a view of my stock resonator:

You can really see the exhaust going from a 2 1/2 diameter to 2 1/4 as it feeds into the resonator. I had the guy cut the pipes right before the tapering so I could keep it at a nice 2 1/2 inches all the way through.

After the resonator and pipes were cut, I took a pic of the opened up exhaust:

One of the things that I found very surprising was the fact that the Resonator is actually a straight-thru design. This made me wonder how much of a performance gain I would actually see? Hmmmm:

Here goes a pic of the final product right before the final welds were completed:

Overall, I am happy with the results. There is a little more of a drone between 1000-1800 rpm but other than that, I really don't notice anything else. The seat of the pants feel was the same. I am supposing that once the headers get installed, this will compliment the performance.

Also, here is a youtube video of me revving up the car after the x-pipe install. There is a raspier sound which reminds me alot of the Corsa.

Oh, and also, the PO had the dynomax mufflers installed and left the stock ZR-1 tips. I LOVE the sleeper look

Sounds good. You should get the muffler tips centered better for a cleaner look. Have fun.

OMG I am DYING for a license plate holder!!!!!! My plate looks so wimpy and sad on there, I totally agree

If you know of where I can find one, hell even a look-alike will do, it would be MUCH appreciated! Merry Christmas, by the way

Well if the buyer backs out, I can PayPal you $ immediately. Do you also happen to have a link for the filler plate on eBay? I did a quick search but didn't come up with anything....

Thanks for all of the helpful links regarding the ZR1 exhaust systems! It'll definitely make for some nice reading on this cold and dreary Xmas day!
