my version of twice pipes

[madkaw]

Well it's not done yet ,but the hard part is done ,I hope. I need to make a final decision on mufflers or just glasspacks.And the decision on tips-that's going to be tough. I can't wait to hear it run.

lookin good! let us know how things go!

[Cethern]

It look's great!
The only thing I see that could be a pain is if you have to take
out the tranny the exhaust system will have to come out. Maybe a one or two flanges would help.

[=Enigma=]

Nice job there. I can't wait to see the finished product. I'd like to do something similar when I mount my 6 into 2 Clifford header.

[madkaw]

I plan on putting a flange on the mufflers right now ,but still thinking about that. As it is, the whole set up just slides off the header in one piece.I would hope that after disconnecting my mufflers i will be able to drop the exhaust down in a complete assembly since the pipes do not run over anything.

[geezer]

Nice job! Maybe a flange coming off the header pipes would be a good idea. They won't just slide off that easily after a while, especially if they are clamped. You could still drop it in one piece easy enough since you have good support at the halfway point, at the X-crossover. For transmission removal you would be able to undo it at the flange and swing it over and out of the way enough without dropping it completely. Keep us posted on how you finish it up.

I used stainless steel band clamps from Summit Racing The work great and allow you to take it apart when needed.

So Marty,
those clamps sqeeze the pipe over a larger area so you don't crimp the pipe?That would be sweeet and improve my chance of pulling the pipes off in one piece. I've seen those clamps before but have no experience with them.

I have pretty much the same headers as you, and the clamps that Marty posted are the ones I plan to use when I get around to installing my headers. I feel they will make for a cleaner install.

I like how you did the system. for me a pair of supertraps coming out where the BRE's did in the center would look kinda cool..

[madkaw]

I've been checking out these clamps at summit and Jegs. I guess they have 2 types-one a lap type and the other a butt type. I'll have to figure out how they size the lap type to install my pipes to the header. I am using the sleeves from the collector MSA provided that slide over the header.
The butt type will be nice for in the back for seperating the exhaust system in 2 pieces. I'm glad you guys brought this up about the clamps.
How about some tips on glasspacks. I was wondering how the exhaust tone changes with the length of a glasspack. I will be able to fit from 12" to 18" glasspacks .I assume the longer the can ,the quieter the sound??? How much affect does the tip have on the sound???

[red_dog007]

Wow, those are some nice pipes. That would be a dual setup that I would love to have.
What diameter pipes are those?

Looking great!

Yes Steve, longer is quieter on glass packs. My red car has a single 24" glasspack on it. The muffler is 2", the pipes are 1 3/4". (Not my favorite part of the car, performance-wise. But that's what the original owner put on it. And after all, it's only a stock L24.) Anyway, with only that muffler on it and the small diameter pipe, it's not too loud, and has a nice mellow tone. Burbles and pops on deceleration, too.

Your pipes look like 2 1/4" to me. If so, I'd put 18" on it for street driving. The larger pipes will make it louder, so more muffler might be better.

[madkaw]

Thanks Arne,
thats the kind of info I need since I don't mess with exhaust too much. Those pipes are 2" all the way. I wanted to keep them small but also match up with the MSA header collector. I think anything bigger is way overkill. I am only running the p-30 but it is modified. I was looking for a different sound and look out the back. Plus I have only heard good things about crossovers so I incorporated that in the mix. Plus with my set up ,I can split the pipes on either side of the gas tank. Who knows, maybe the performance gain will be more then enough to offset the additional weight:laugh:
I feel lucky that it has came out so good so far since i only screwed up one mandrel bend.

[Arne]

Sounds good. With 2" I'm pretty comfortable that a pair of 18" should do the trick. The cross-over should even out the pulses and smooth the exhaust note. I'd love to hear it when it's done.

[mars23z]

The system looks great I cant wait to hear it. I want that system on my Z. Its looks alot better then the one from MSA and looks like it fits better to. Good luck I hope to do one on mine this summer at my local custom shop.

[madkaw]

When I get the exhaust completely done ,I would put down a complete list of pipe bends i used. I ordered everything from Stahl Headers , there prices are reasonable and there were friendly to deal with. The pipe is 18 guage which was fine for me to keep weight down . And I was hoping to use this set-up as a templete for maybe a SS version later. The cost was atleast double++ for SS and I would have been pissed screwing up a 40$ piece of SS pipe.
