I was just wondering if anyone had any experience with Speed Engineering X-Pipes? Not the one's that work with their headers, just the one that works with stock exhaust and replaces the secondary cats. Looking for info on fit and sound. Thanks

I just ordered one tonight for $275 shipped to my door. I will report back after I have a chance to install it. It looks like a clone of the Corsa double helix.
Sausage_Fingers - thanks for the note, yes, please let me know what you think of the fit and sound. They look pretty decent.
Good luck with the install.
Good evening gentlemen. I posted my mini review of the Speed Engineering x-pipe in another thread and thought I'd link it here for you. Long story short, I'm pleased with it. Sounds great, inexpensive, install wasn't too bad. I'd definitely recommend not doing this on jack stands like I did if you have another option. Your back will thank you. If anyone has any other questions, let me know and I'll do my best to answer.
I had a set of header/x pipe on my C6, I got tons of complements on the sound. I've got a new set for my C7 I just got back from the ceramic coater. Goes on next month (with the A&A kit).
Last week, I also installed this Speed Engineering "Double Helix" X-Pipe on my wife's 2019 Grand Sport M7. We used Race Ramps up front and 3 ton jackstands in the rear to raise the car off the garage floor. This is a very nice high quality single piece design and the fitment is perfect. I replaced the front donut gaskets with Fel-Pro PN 61013 purchased on eBay for about $18/apiece. Just make sure you check for leaks; I had to torque down the rear band clamps very tightly to get them to seal. The sound is much improved with open valves and by the seat of the pants it feels like it pulls harder through the gears. Overall, its a great bang for the buck mod for only $249.00 + shipping.
Nice tread always helps when someone posts there new DIY'S. I have already order mine just waiting for it. My question would be about the powder coating, is there a difference in the protection from heat on which color you get. Years again I had a motorcycle with a bright silver coloring and rough coat. I was thinking about getting the black color, and also using some wrap too. Thank you for a reply in advanced.
My job is done. I was going to do a write up on the whole project, but the headers were fine. They went in fine, fit fine. They don't seal 100%, I might try to adjust it a little more. I was going to put a few heat cycles on it then re-tighten. A&A kit just tuned on Tuesday, so it's still very new.
As for the coatings- This time I went for a "burnt bronze" color vs the classic "shiny silver". The gal at the coating place had both in the highest temp range. They do two coats on the outside, one coat on the inside. On my C6, I also had Speed Engineering headers and x-pipe. I did the silver then.
Comparison-
The burnt bronze gave it a more custom and personally I think more of a classier look.
The downside is- if you scratch the burnt bronze, and they scratch VERY easily- it sticks out like a sore thumb. When you scratch the silver, it just looks like a scuff.
The standard ceramic coating is pretty darn soft. I've had a couple other projects that used it, and it's soft, not like you'd imagine a "ceramic" surface to feel like.
What I did was- wrap the headers with several small pieces of "crash tape". Make sure you use small pieces to make it easy to take off each one once its up in place. I got a roll to protect the fenders, etc. Worked perfectly. Wrap up the bottom of the headers, push 'em up from the bottom, wiggle in place- once the couple bolts are in to hold it up- peel off the tape. It's a life saver. Before it was time, I wiggled up the passenger side to see fitment and put a few scratches in the coating.
With a good ceramic coating (not some gimmick) you shouldn't have to wrap the headers. You're just asking for problems. They retain water, possibility of coming loose after a while, etc.
I also put a small starter wrap on- probably not needed after I had it all together. The stock heat shield looks like it does a pretty good job. If you have any questions, reach out. All this is still pretty fresh in my mind (since I stressed about it for months).
I installed the Speed Engineering X-pipe on my 2017 Z06 along with Corsa Extreme axle back exhaust. The exhaust note is definitely louder that my 2018 Grand Sport with just the Corsa Extreme axle back exhaust. I was hoping there would be more popping sounds with the addition of the X-pipe but that wasnt the case. The only issue I've had with the X-pipe is trying to get the band clamps to seal to the axle back exhaust pipe. Torqued to 45ft-lbs and I still get a leak on both pipes where the clamp hour-glass doesn't push on the pipe, so there's a leak. Ordering Corsa 2.75" bank clamps as all of their connections don't leak and the hour-glass is pressing against the pipe as it should. I'll update when I get them put in.
The only issue I had with the Speed Engineering X-pipe (the one designed to connect with stock exhaust) was that the distance between the front 2 pipes didn't exactly match the head pipes. And since the X-pipe has a tie strap between the pipes there isn't a lot of flexibility to make the connection. I would say the spread was off by 1/4" or so. By alternatively tightening the flange bolts it pulled up fine. I had no issue with the rear connections.
Yes I also had leaks too. You can try getting exhaust pipe sealer it comes in a tube and you can get it on line or your local auto part store. You will need to disconnect the pipes where it is leaking add about a half inch strip around the circumference of the pipe, and reconnect the pipe torc it down. Then let it dry for approximately 24 hours that should work. The moisture at start up then should come out the back of the cars exhaust exit.
I have the same issue with my Speed Engineering xpipe and Corsa rear. The connection doesn’t tighten. I can pull the rear right out of the clamp. I had to wrap tape around the hangers to prevent it from sliding.

Just curious if the Corsa Bank Clamps worked for you and eliminate the minor leaks? I just ordered the SE x-pipe and also going to order these clamps to use instead of the clamps that come with the X-Pipe. My question is you mentioned that you ordered the 2.75" clamps, did those work well or would you recommend getting the 3" clamps? here is a pic of the clamp...
The Speed Engineering xpipe is 3 inch piping I believe. However the rear sections are 2.75”. Are you getting a 3 to 2.75 inch stepped clamp?
according to the website for the 2.75" lap clamp, the smaller side is 2.75" and the larger pipe is 2.87", on the 3" lap clamp the smaller pipe is 3.00" and the larger is 3.15".
I don’t think either would work. If the xpipe is 3” OD at the outlet and axle pipes are 2.75” OD at the inlet then you’d need a clamp either ID of those two measures.
Speed Engineering confirmed the outlet pipe outside diameter is 3.0". This is probably why we're all having loose connections with the clamp not sealing. You're stuffing a 2.75" outside diameter axle pipe into most likely a 2.875" inside diameter of the x-pipe. I think I'm going to try a 3" ID to 2.75" ID clamp and see if I get better results. Most likely I'll have to cut an inch or two of the axle pipe to keep my tips tucked under the bumper.
Speed Engineering X-Pipes - any good?
