Invidia Catted Downpipe!
I've read quite a bit about trying to keep the exhaust heat inside the pipe. I can't describe in detail what it's all about...but I just know it's good for turbo cars and applications. Knowing that, I headed on down to my local Pep-Boys for some good 'ol DEI Exhaust wrap! I LOVE Pep-Boys. Granted they have terrible customer service, over charge and have employees that know nothing about what they are selling....they do have a gem inside every now and then!
So 50 Yards of Exhaust wrap later...I ended up with this:
I also splurged and went with the DEI stainless ties. I'm not to fond of these. It was my first time using them, and must say, I'm not impressed. I'm thinking I may have to switch to some clamps later down the line.
The install is pretty straight forward. You just need to find all the bolts and remove them from the stock DP. The bolts are easy to find and there are several writeups on how to do it. The best advise I have is make sure your STRONG or have a breaker bar. I had neither, so it took me 4 hours to do the swap. The main problem was, I thought I could get around removing the bellmouth section without having to take my TMIC (Top Mount InterCooler) off. WRONG. So that delayed me a little bit. Then there was the issue of trying to break off all the bolts that held the DP to the turbo. I did use a penetrator spray on it and let it sit for a good 10-15 minutes. That is what I'm hoping led to my success of removing the stock unit. To my surprise the hardest of all the bolts to remove was the hanger bolt on the bottom of the car. My best guess as to why it was harder than the rest, is I had no leverage to get at it. I was laying on my back and hands over my head trying to get it. Finally I gave in and pulled a hammer out and beat the heck out of it till it finally broke free. In the end this is the comparison:
Less restriction and nicer flowing....can't go wrong!
And the best picture I can get of it installed:
On a side note, when your using penetrator on your bolts...wipe the excess off. My car looked like it was on fire in the engine bay the next day when I took it to work. I had to stop at least 2 times because I thought it actually must have caught fire. 2 days later and I can still smell the stuff! I'm hoping a good air freshener will help eliminate it.
After this I went ahead and flashed may stage 2 OTS program from Cobb. I'll get a few more parts put together and then get my pro-tune done. I've one had the chance to get 1 good push on it so far. And with my AP I clocked a 19.6psi reading. I was formerly at a 18.2 max psi. So the new program upped my boost and I can tell for sure. The rumble is a litter more pronounced, especially when starting the car up. I've also been told people notice the car more when I drive by them. So I can safely say the car is louder now because of it. It's not obnoxiously loud however, which is what I was going for.
More to follow.
