355 secondary bypass pipe under $500

I want to put flow through primary and delete secondary cats on my 355. I started looking at the secondary bypass pipes online the price is outrageous. I called a shop in Detroit that builds exhaust systems for any car. They do a lot of work on high end race cars. The guy that owns the shop is highly regarded as one of the best in the state.
He looked up pics of the oem and and aftermarket pipes called me back and said this is very easy for me to do.. he said he will need the oem pipe to work off from. quoted me $500 if he has to build the flange $600. If I buy 5 sets $350. Mandrel bent ...guaranteed
10 min of research saved me $600....

 

If he had a oem one to go off from he can build it... this is not a complicated piece I have no idea how people can justify $1200-$1500

 

I'm going to have a set built...he told me if I bought 5 he would discount them..He needs my oem pipe to make a jig or whatever he needs to duplicate all the dimensions. Pete asked about his 2.7 I am not sure if the pipes are the same. He may need Petes to use as a template.
I just thought about this when I looked them up online.. I was like WTF? $1200 for a couple of pieces of pipe and some welding....any shop that makes custom performance exhausts can build this for next to nothing.. and they can and will

 

I was just on the phone again with Jim Gautz at Gautz Enterprises. Pete he says a bypass for your car is not a problem. He also said they build all the prototypes for Chrysler,Ford,Chevrolet and Toyota. He said he can easily build flow thru cats and he builds custom headers so he said he can build 355 headers that go in the clamshell. One thing he did say is he might have to put for off road use only. Thats for his own liability protection.

 

Dave I want to replace my headers before they crack and get them on a shelf. With these aftermarket ones they are bullet proof and no more worries. Fabspeed makes O2 spacers to minimize throwing a CEL. The flow through cats and deletes will boost performance and should reduce engine bay heat. I am also going to put a challenge grill on mine for more ventilation

 

Thanks Dave I was looking at them and thats the route I am going also

 

Dave I didnt see anything in that thread that mentions aftermarket challenge grill. I will keep my oem one but for driving around the aftermarket one will be fine or I'll get one from Russ at ferrparts

 

good info thanks Dave

 

Guys I will get mine made and report back I wanted to wait until fall but the pressure is on I didn't want my car down in the summer. Oh well

 

Some of these shops only build exhaust for very high end cars take a shop like Jim's they build them for American hot rods to Porsche and rolls Royce they have a lot more people paying the bills. These by pass pipes are simple for them. Look at the primary by pass pipes. Think that's hard for a guy whose been in the business for 30 plus years ? Come on
