Introducing BISKWIK

[Cramer4918]

Starting the process..



I used a section of the straight pipe to line up on the bottom of the frame to check my ground clearance.


Fitting the minor bend before the turn towards the back.


Making the turn back.


Plenty of clearance for the tire.


Who knew Painter’s tape would be so versatile?!?!


I used the boxes to assure there was plenty of clearance for the exhaust since they are right at the height of the bottom of the frame.

I bought some stainless wire for my welder and was able to get the pieces tacked together. I know it’s not pretty, but I’m working with minimal tools.

My plan is to make the exhaust in three sections. I will use stainless clamps to join the sections together so that I can remove them if needed. I am going to take the sections to get TIG’d together.

I know the tacks are bigger than needed. I’m still learning to weld properly. The guy that is going to TIG the pieces together said he can work with them. I am hoping to be able to watch him and I will possibly grind some of the tacks down as he gets some solid welds in.



Not too shabby for my first time building an exhaust.



I just need to commit to either side exit or all the way out the back now.

In the middle of getting the exhaust mocked up, my new to me injectors arrived. I did some research on the ones that were installed and found out they were only 24# injectors. They may have worked for my application, but they would have been maxed out in duty cycle according to the flow calculator I used. The new injectors are 50# GM injectors. These will be more than adequate for my setup.

The injectors that were installed when I got BISKWIK.



The 50# injectors with EV1 to EV6 adapters and injector spacers in place.



Hopefully I’ll be firing it up soon!!!

Happy New Year Everyone! I hope you all had a Great Christmas and great New Year!

A small update for BISKWIK. I didn’t work on it much while the kids were out of school, but I was able to make some progress.


Passenger side exhaust ran to the back.




Decent clearance for the tires. I am running 285/35’s on a 20X9 wheel.


I need to make turndown for the mufflers still.

I managed to finish the driver’s side as well.

I had to order two 30 degree elbows to finish this side. A minor four day setback.





Not too shabby for my first time building an exhaust. I have to get hangers in place and then I’ll take it all off to get TIG welded. I am hoping g to have it all back on the car 100% by next weekend. We shall see.

The journey for cutting the tubing was painful in the beginning. Making clean cuts on the pipe was challenging with a 6” angle grinder. Not to mention, getting the tubing cut square on the bends. Initially I wrapped painters tape around the tubing and marked them that way. Most of the time I would end up making adjustments to my cuts to get the ends to mate up properly. That was time consuming to the say the least. I then discovered the technique of using a zip tie cinched down around the tubing. You could move it however you needed along the elbow and mark it. That allowed me to get the my cuts marked perfect every time!



It was like magic!

Another trick I learned was to use a tubing cutter. I found one that would cut up to 2 5/8” on Amazon.

It helped make the cuts perfect every time! It was a little difficult once the elbow got tighter, but it worked on the 30 degree elbows with no problem. I’ll see if I have any pics of that.

Hopefully that info helps whoever would want to tackle their own exhaust.

I used the ziptie trick with the headers and exhaust on the TA. Worked great as you've seen. Your exhaust looks great.

Side note, I had no idea Flowmaster made a straight through style muffler like Magnaflow until I was hunting for exhaust for my C10. I wanted low buck because I'm cheap. I love Magnaflow but found the Flow FX mufflers for half as much. Hopefully, I like the sound.

Keep up the great work.

Thank you for the compliment! I do appreciate it!

I definitely learned a lot during this process. I am hoping to improve my welding skills for future projects.

I like the Magnaflow mufflers as well. I am hoping these Flowmasters sound as good as them. They appear to be the same internal construction. Once I get it running, I’ll try to post a sound clip.

Nice trick and cutter. Wish they made that cutter for a 3" stainless pipe.

Curious if you considered using an expansion joint and if so why you chose not to go that route. Great looking work BTW

Are you referring to a lap joint similar to below pic?

If so, it is because the Builder’s kit I purchased did not have that option and the closest exhaust shop is an hour and a half away. That’s why I used the butt joint clamps.
