I'm an "expert" welder. I purchased a MIG welder about a month ago and after a few practices successfully welded in a patch panel on my tunnel to cover a hole someone cut for a stick shift or just to get some fresh air into the cabin (LOL). The weld didn't look too bad either if you don't mind the globby look. Seriously after grinding all the high spots down it was fine.

Now I'm cocky and would like to substitute 2.5" pipes back to the mufflers rather than keep the 2.25" that are on there now. I've got a 454 that's set up for daily street use and I can't help but think I may be choking the engine somewhat with the smaller pipes. This is getting long-winded so I'll cut to the question:

Is there someplace that I can get the pipes inexpensively so I can weld them together? I know companies make kits for things like this but they seem pricey to me for just a little exhaust pipe. I live near a major city (Phoenix) so I have access to all the normal auto stores (Pep Boys. Checker. Napa. etc.)

I know the pipes have to go where the old ones were so I would need the appropriate assortment of different bends and angles to accomplish this.

Any suggestions? I probably need the 2.5" exhaust from the headers to the mufflers to adequately keep the engine breathing don't you think? Or not?

Try this!! They are even located in Scottsdale. They aren't cheap but are mandrel bent and flow great. They also fit pretty nice. But while you're at it, go 3"....

You could also try Summit for a couple of 4 foot pieces of 2.5 or even 3.0 pipe which runs for $10.99 to $13.39 and then take your old pipes to a local shop and see if they will bend it up for you, or you could by a complete system from Flowmaster or Borla.
Just a thought.

Hey neighbor, NAPA only sells straight pipe. Summit or Jegs sells various J and U bent pipe. They also have an S pipe kit from Hedman, I think. I used that on my chevelle, but I wish I would have just bought a kit. I have the 3" TA performance kit on one of my cars if you want to see it. I'm going to order the Flowmaster 2.5" kit with the delta flows for the other car. Email me if you want to come by.

In retrospect it appears I may have been a bit overzealous in wanting to craft my own exhaust (the wife says I'm just cheap!). The kit's may not be so pricey after all given the alternatives. Time to start saving the Franklins.

Thanks everyone for your advice and help - I appreciate it. Jon

Years ago I was going to do the same thing as you. I bought new Walker straight section 2.5" tailpipe material and mufflers and was going to have a muffler shop bend them for me because they didn't have 2.5" in stock.

The muffler shop pointed out that the pipe they bend isn't standard straight section stuff, but rather pipe made for bending. They grabbed a section of their stuff and a section of what I wanted bent and yes, indeed, they were different pipe. Their pipe was, I think, heavier. Seems that the straight stuff I wanted to use would crimp because they didn't have a mandrill bending machine.

It's worth thinking about! pdq67

NAPA carries mandrel bent tubes in various sizes, lenghts and degrees. I have used them on a few of my cars. If you can weld it, go for it. Nothing feels better than doing it yourself.
