Use mandrel bends and weld them together like you would making custom headers. Local muffler shop benders will kink or undercut the back side of the bend where it follows the shoe. I doubt any shop would have an expensive mandrel bender...maybe, but somehow doubt it. They are usually used by manufacturers doing high volume stuff.

How about doing an X-pipe like a Dr. Gas kit? That would give you all the pipe & bends to get from the headers to the mufflers.

 

Same thing the custom shop said today.I can't see putting $1,300-$1,500 IN A EXHAUST.Im no welder so that limits my choices.I know they can do a 3 inch and if there isn't to much difference between the 3.5 and 3 inch in hp I will go that way.It's becoming a pain in the rear.

 

Driver,

Too bad you are so far away. I have a full 4" mandrel bend system that I will let go for $200.

 

I would be all over it if you was closer.One can never have to many tools.

 

10secbu it looks real nice. Mine would be pretty simple to do really.Down the sides coming out in front of the rear tire.I have to do a way with the big and heavy 5 inch.It's got to go.

 

Well, the 3 1/2" Dr. Gas X-pipe shown in that pic sells for right around $240.

 

I was just now looking on jegs and they do have some 90's and J pipe that I might be able to work something out.

 

One more question? Did you do the welding on your system and if so what type of welder did you use?Instead of giving a custom shop a grand maybe I should invest in a welder and learn to weld myself.Im sure I'll get plenty of use out of a welder over time which will pay for it's self.That's if I can teach myself.

 

Yes, the Dr. Gas system requires the joints to be welded, but it's fairly easy with experience.

I originally welded it together with a Mig machine, but this last time around I rully Tig welded it for a cleaner, neater appearance.

The tubing is 16 gauge wall thickness aluminized, so some grinding of the surface at the welding points makes welding much easier. It's also a good idea to clean the inside of the tubes out prior to fabrication & welding as the mandrel bender leaves a grease film inside the tubing.

 

Thanks,which is the easier one for a learner to work with?MIG OR TIG?

 

Mig is easier to learn for a beginner.

 

Thanks,I see they have a price tag as well.

 

Driver,

I built my 3.5" system myself using 3.5" - 45 deg. mandrel bends and straight pipe and pieced them together and then welded them. I have a MIG and TIG welder, but was in a hurry (3 AM trying to make a race)so I just MIG welded it to save time.

You might check with a local welding shop on getting a price just to weld up the pieces after you fit them to the car. You would just need to fit and clearly mark how the pieces should be oriented. I would think that you should be able to find a shop that would do it for a couple hundred bucks. You will need to be sure you fit the joints nice and tight.

You should be able to get 3.5" - 45 and 90 degree bends from any truck shop that sells class 8 truck parts

 

Thanks dragracer.I found all the pipe at jegs but they don't have 45's.Maybe NAPA down the road from me might.Thanks Again,Bill

 

Well I went out today and bought a LINCOLN MIG WELDER 135 amp.Now learn how to weld!! HAHA.Wasn't cheap but it's a good brand name so it should last for years to come.I did some welding on used junk stuff which I did ok but no where near good enough to weld on my exhaust.Any pointers on mig welding would really be helpful.Thanks,Bill
