I'm almost at 500 miles and change the oil. Then I'll do a data log to send to Blackbear and update a few things. I haven't done any videos due to my camera, but also I've been chasing down a knarly exhaust leak. The connection for the ARH to the factory system doesn't play well together, but I adjusted it today. I'm planning a trip to my exhaust shop this week to install true, 3" exhaust. A downside I've had, somehow I didn't notice that my tailpipe shifted and it burnt a roundish hole in the bumper. Other than that, I can't believe the power this thing makes. I'm gonna have to borrow a phone so I can get videos for you guys

I thought those L9Hs ran 3.5" exhausts?

The factory y pipe was tiny but it stepped up to 3.5". My ARH long tubes came with cats and have 3" pipes that go in to a collector, that then bolts to the flange going to the factory system. I have always planned on going to 3" true duals with hidden tailpipes. The 3.5" system flows and sounds good, but I can't stand the sound of both banks converging into a single system.

A picture from last year, but under that cover was the wrong flange to mate to my stock exhaust, it had a ball type end while my stock system has a flange. We did a chop and weld of the flange to make it all work, but it leaks in a few spots. So that's why I'm just going to do the true duals now instead of later.

Ahh, I understand now, thanks Mike. Glad the project is working out great!

Running an H or X pipe? Or muffler with X built in?

Running an H or X pipe? Or muffler with X built in?

Definitely an x pipe. I used to run the muffler with the x built in on other vehicles I've owned, but I'm leaning towards a built in x pipe, with dual corsa sport mufflers. I'm also planning on using resonators, maybe like these:

I don't know how quiet you're trying to get it (Obviously not as quiet as stock!). But, for reference, mine (no cats) was obnoxious inside and outside with just the 18" Magnaflow clone, which is a straight-through, packed style muffler. Now, with 40" of that type of muffler, it's maybe just a little louder than stock. With the cats and the 18" muffler, it was perfect, IMO.

Work has been so crazy lately that I've not gotten any videos yet. I am also still waiting on a tune update from Blackbear, I sent that in about 2 weeks ago. Other than the rear o2 sensors throwing efficiency codes, it's running awesome. My city driving mpg dropped to 7MPG on E85, I think it may be dumping just a little too much fuel... But I'm sure my data log to BB will show if that's the case or not. As for my exhaust, I'm still at square 1 with that, mainly because I haven't had the time make up my mind on what I want, haha.

C'mon @mikeyss gotta step up your video game . She sounds like a beast.

I will try and post something this weekend, because she is a beast. Living at a mile above sea level doesn't seem to affect it anymore, but I'm sure if I was a sea level... I wouldn't have rear tires anymore. Oh, one MAJOR annoyance it has.. the shift from 1st to 2nd with 75% throttle causes TC to kick in and kill all power. I'm on the fence whether or not to just pull the TC fuse and live with the warning lights.

Torque Convertor?

 

[mikeyss]

Torque Convertor

The Circle D 2600 stall I have definitely pastes me in my seat, I'm guessing it's part of why it's trying to spin during the shift. Plus the harder I'm on the throttler, the harder the shifts are

I'm not completely schooled on tc. I have a 3000 stall Circle D in mine. I floor it a lot lol.

Oh.... I'm sorry I misunderstood you... TC = Traction Control is what I meant in my other post

Lol, ok--makes better sense now.

Mention that to BBP. I’m sure they can assist with taming it a bit.

Blackbear sent my new tune files this week, and all I can say is holy shit!!!! After I replaced the engine the tune they sent felt good... But after I sent the data files to them to dial it all in, and raise shift points to 6400 RPM since that's what the cam likes.. This thing runs amazing. The 2600 converter also plays nice and knows exactly when to lock and unlock.

I want to shoot a video of 0 - 60, it's harder now that goes like a bat out of hell.

The exhaust is causing me a headache. I want Corsa, but they don't sell JUST the muffler. All exhaust shops here won't do true dual 3" split rear exit saying space is an issue. So I am thinking I'll have to piece this all together myself. The only thing I can't seem to find is 2 Corsa mufflers.

Awesome! I’m glad you got the tune updated! Sounds like it’s all coming together.!

Have you tried contacting Corsa directly?

 

[mikeyss]

Have you tried contacting Corsa directly?

I haven't tried to contact them, only because I've searched google high and low looking for any situation where Corsa sold just a muffler. There was a DB series, but that dissolved. I am looking at borla s-type crate muffler, or the Corsa 3" dual in/dual out muffler that goes on a Raptor. I have Vibrant resonators that I plan to use at split rear exit. Since I gapped the rings for supercharging, I won't settle for anything less than 3" true duals, and I'm finding I'll have to Frankenstein the dual tailpipes from Silverado ones.

I'm thinking of getting these, they look nice and... I kinda want to quiet up that awesome cam/valvetrain I have. Has anyone ever tired these?
