secondary cat delete.

[Lobo1186]

im just going to have a local shop cut me some pipe. I see no need to pay fabspeed 500 dollars for something I got quoted 40 per side... but I had to cut the cats off myself so I guess I pay the price in other ways.

there is actually an alternative:
get a set of secondary cats from a junkyard. Now get rid of whatever's inside the cat housing (I leave it up to your imagination on how to do that).
Now you have something which looks totally stock, was very cheap and has the same effect like bypass pipes (more torque)

that was a thought. BUT I found a place that bent pipe for 40 dollars total. So a 500 dollar mod so far cost me 40. Hopefully they will match up well. Ill have it done today, I have a AX tomorrow so we will see. the results.

Is that pipe stainless steel pipe? If not, expect to replace rusted out pipe in short order.

Also, did they fabricate the triangular flange on those pipes that mates with the headers like the fabspeed pipes? If so, I'd say you got a very good deal.

it would have cost me an extra 50 bux for the triangular flange. but since my box is a 2001 and the bolts holding that whole gettup together are rusted solid. I did not want to bother. I cut the secondary cat out and slid the new pipe over the other luckily the entrance pipe to the secondary cat is 1.5in (or so) and the exit is 1.75 so the whole bypass is just 1.75 and it fits snugly over the 1.5, as far as material... idk whatever the exhaust shop had, do exhaust shops use normal or stainless? IDK. but it isnt polished and it was only 40 bones so ill let it ride. but i do need to pick up some clamps and fix some small leaks.


so in the end if you have the money to burn go ahead with the fabspeed... but if you can DIY and you dont mind DIY then this I would contend is the way to go.

Thats a really good deal, after all its just a piece of pipe that doesn't have to cost you 500 bucks unless of course you want a shiney ss piping collecting dirt under your car. Im doing the same on my car next week (that or some straight pipes).
P.S. dont worry about it rusting out on you any time soon, stock piping on boxster is just a alluminized steel too. I had a exhaust shop fabricate a cat-deletes and H pipe for my 928 from alluminized steel and 6 years later - just some surface rust.
Just my 2 cents

Sounds cool. Being that you're in Cali, and not in the Northeast where I am where there's salt thrown all over the road in the winter, you'll prob be just fine with the plain steel pipes. How do you like the extra sound?

[Lobo1186]

al83s- yes it is true that everything under there is rusted... whats another pipe lol. however, I do have some small leaks so i may get it all welded in... not sure but all I do know is i will be testing it tomorrow at the AX.

Boxtaboy- It has been fun so far. easy yet time consuming. makes you appreciate the car (to me anyway) I like the sound so far but i will like it more once it stops leaking. its funny even my OEM exhaust points ar leaking slightly ahha.
