Hey guys, need some opinions/advice on welding my custom B-Pipe to extend it at least 3-4 inches. I have the JIC Full Titanium Exhaust and as you all know, it is shorter and is meant for the JDM Rear bumper. I was thinking of welding and adding an extra 3-4 inch of piping to the titanium but, found out how much it cost just for the titanium! Really expensive!:pissed: So I was thinking that I could weld it on the B-Pipe instead and extend it out.
My question is, before I take it to the shop, would that be a bad idea? I know that it may alter a lot of things but, I love this exhaust and would much appreciate it if it didn't BURN or MELT my rear bumper!!!:)
Any help or advice would be great!:)

Heres a pic of what it looks like today:



Bought the Attain Carbon Fiber exhaust guard to mask the burnt area...

Disconnect the b-pipe from the catback, push it back and see if it gets in the way of anything. It may hit somewhere.

^^JDM bumper is wayyy expensive! If I can find one for a decent price, I'd snatch it up...I would go that route but, don't want to have to rob a bank to have it.:)

I'm sure that it will hit something, but my questions is, "is it worth doing?"

i'm not sure, butttt i know there are aftermarket Y-pipes that are a little longer than the stock ones, i'm not sure WHAT ones they are, but i've heard some people complaining that their exhaust sticks out too far with them.
that or just add a little pipe of titanium like you said at the meet??

EDIT: I Did'nt know you had a aftermarket y-pipe, just read your sig =)

cut off the resonator fromt he B-pipe then make that a straight pipe with an extension on that pipe. it wont cause anything to go wrong. the back pressure will still be the same.

I don't think it would alter anything too much. You are talking about an additional 3-4 inches of piping that exhausts designed for USDM bumpers already have. Would it be possible to create a new b-pipe entirely? You could sell the one you currently have to offset the cost of fabricating a new one, and when all is said and done, you'd have a new piece of piping designed exactly for your application. If you ever decide to sell your JIC rear section, you can sell the b-pipe with it and have the marketability of a full cat-back.

Extending the b-pipe is one thing, but what about the hangers, shape of the pipes?

yeah i think if you extend the bpipe your exhaust will actually hit the bumper because the angle will change (i think)

well when i had a b pipe on my car it really changed the angle of the exhaust

Thats a good idea. I hope that it works out. Thank you for the insight!:)

Shoot! You're right, I have to see what that will do.

I hear you. Thanks.

Lol! Thanks for the tip Omar.^^

Usually $300-550 depending where and who you get it from.

I'll have the shop look at it and I'll take a closer look to see if it would be a "go" or a "no."

Thanks everyone for your ideas...any others?

Take it to any exhaust shop. They should be able to take care of that easily without messing with the Ti parts.

well since we are on the topic, what kinda cost are we looking at here to cut out the resonator of the bpipe and replace it. Not to add extension for i have a HKS cf-ti axle back and want the thing a bit louder. This be cheaper than buying a new b pipe? cause the ones i have seen new are around 120.00. also can't find any used ones.

Should be no more than $60.00 tops. I had a whole muffler and new piping installed in my DC2 for less than $50.00. So adding bout 3-4inches or replacing the cat for a straight pipe shouldn't be much at all. Maybe you can buy the shop guy lunch and call it even? Lol!:bigSmile:

Ok, so a paid a guy fifty bucks to get res removed and he did. Clean weld on all spots and still fits great. Sounds sweet but i cant wait to put HKS back on it. I will put exhaust, hood, trunk, front, grille, and all my other stuff i bought over the winter on in 2-3 weeks. hopefully. cf
Hood needs repainted first.
