I'm back with another round of questions. I am in the final stretch of finishing what I want to do with the car, but I am on a bit of a time crunch. I purchased Speed engineering Long tube headers and X pipe, as well as a Borla ATAK axle-back exhaust. However, the X pipe is on back order and it keeps getting pushed back repeatedly, leaving me in the situation I'm in. I need to get an X pipe here as quickly as I can so I can have my car tuned before I take it on a vacation next month. However, I noticed that any X pipe I find has a bolt on flange for the stock manifold, and the headers I have do not have a bolt on, they are designed to use clamps. Are there any options for X pipes out there that I can use to remedy this, or am I basically toast until the x pipe I need arrives? Also, I know that I will need to get some sort of adapter either at the end of the headers or at the end of the mid-pipe to connect it to the exhaust. I didn't do enough research before purchasing, and I am in too deep to go back and change anything. If I'm toast and there are no alternatives, I'll just have to cough up the money to get my car tuned twice, I would just rather avoid having to do that at all. Thank you for any help you guys can give, and have a good one!

My Equipment:
Speed Engineering long tube headers (3" outlet)
Speed engineering x-pipe (MIA - need alternatives)
Borla ATAK axle-back exhaust (2.5" inlet)

 

When I bought my SE x-pipe it came with 3 different sections for all C6's.I would assume they still do so that part isn't an issue.As far as a different x-pipe that would work,I have no idea.Sorry I can't be of more help.

 

You need the SE pipe or custom.
If you are adimate about tuning the car for some reason, just get it tuned open headers.
The tune doesn’t change for exhaust (including headers)

 

the only reason I'm so set on getting it tuned is because I just put a cam in it recently. If I were to get it tuned open headers, that would be no different than getting it tuned with long tube headers through the exhaust?

 

correct. The length of the exhaust makes no difference on tune.
Why not poll your tuner for this info? That’s what you are paying them for.
This is the second post I have seen on this topic with the same results posted.

 

I did see your post on my old thread, I just wasnt sure if you meant having vs not having cats would make a difference. I thought you were talking about the exhaust itself. I haven't messaged a tuner about it because I'm still looking for one close to where I'm at. I've been gun shy with picking one because I have a bad habit of rushing into things without enough research 😅.

Thank you though, this honestly lightens my stress quite a bit. I can just wait for the mid pipe and put it all on then but still get the tune now so I can at least drive my car around between now and then.

 

It’s all good man.
Yea exhaust should be the least of your worries.

 

Awesome, thank you a ton!
