All I can say is wow. Big thanks to Cobalt Addiction for their good quality products.
Everything bolted up nicely. It took me like 3 hours or so to install. Man it's loud.
I will have some pics by tomorrow and i'm working on borrowing a camcorder for some sound clips. The exhaust has a very very deep tone, not raspy at all. The butt dyno can feel the difference. I'm going to hop on a dyno again in a couple weeks.

Again big thanks to Cobalt Addiction. Your products are awsome. Thanks Crate Engine Depot for the GM sport cat back. You guys rock too. Pics will come soon.

P.S. It's the 2.5" downpipe w/cat and GM sport exhaust 2.25" not touring.

Exhaust Video Link!

you gots the 2.5 dp with cat right ct?

CTCOBALTSSS

Yes sir. It sounds really good.

Get some pics up broseph,

how noticeable was the difference in diameter from their header (collector) to the DP?

distillion

nice, almost gonna have the same set up except i have the gmpp exhaust manifold, any change in boost?

sheek360

isnt the gm cat back a 2.25"?

distillion

2.25, flows better than stock and the most recnet dyno was about 12 ponies over stock.

CTCOBALTSSS

Not much difference at all, it bolts right up mith minimal overhang.
Yeah bro pics will be up later tonight or tomorrow.

I haven't really got on it yet like 7k or anything. I want to get that cat coated before I start throwing a rich mixture at it. Running rich will eat a cat in days. I'll get on her at lunch today and let you know.

yeah.... but it def flows better than the stock garbage we got.... wait til you guys hear my setup... once the cars back together I"ll post up a vid.... sounds like a straight up race car now....
p.s. shot my first fire ball the day before I broke my axles (had to retune meth hitting an afr of 10.4:1) **** was funny

distillion

ya, i guess its good to baby the cat for a bit then hammer it, let us know how it goes, what do u guys reccomend as per wait time until you can get on the throttle?

CTCOBALTSSS

That's good shtuff. OK guys i'll be back after lunch. I'll let you know if there's a difference in boost.

sheek360

I know, bill has that exhaust. sounds good too btw

Matty

Good to hear it all went well. Can't wait to hear the clip and see the numbers.

I love the way it sounds, but I would be sacrificing everything by buying a 2.25" exhaust. That's too restrictive for future mods IMO, but please let me know how it works out with your mods.

CTCOBALTSSS

OK guys I just got on it a little.
I'm still seeing 15.5psi so that's nothing new.
The butt dyno says it worked lovely.

I just found out I can use my boy's camcorder.
I'm going to his house at 5:30pm
I'm going to make a little 1-2 minute video of all my mods.
I'll post it up by sometime tonight.

p7x

^^^^ cant wait

distillion

sick, atleast i have an idea on what mine will sound like.

sheek360

same hear....

CTCOBALTSSS

I made the little video. It's like 30 seconds. The camcorder records to a mini disc so we were trying to get it on the hard drive. I finally got the clip onto the hard drive but it didn't download the sound just the visual. I tried for a couple hours to figure it out it keeps saying .vob not supported. I'm going to keep trying tonight any advice would help.

bigd2114

how about some pics

CTCOBALTSSS

Yeah if I can't get this freaking video to produce sound I guess i'll just post some pics.
It's my pap's b-day today so i'll snap a couple pics as soon as I get the chance. Just a warning though my camera is old school 1.5 mega pixel. It sucks.

1SloBowtie

Any update on pix?

CTCOBALTSSS

Here is a sound clip bro, my boy who was behind the camera didn't get a good shot of the header at all. I'll get pics up tomorrow. This took enough time for tonight.
