hey gang,

I'm finally getting around to installing the duals on my burgundy 98. This has been high on my list for a very long time. I also just installed the rebuilt tranny...trying to get everything done at once.

I got the pipes from Classic Exhaust and I'm very impressed with the service so far. The pipes all seem to fit well and I got the order in only a few days.

Here's my question. Moving from front to back (manifold to tailpipe), how important is it that each pipe go INTO the next piece? I finished the passenger side last night and they all went into each other except the muffler into the pipe over the rear. Everything's well clamped but is this at all an issue? I'm assuming the driver side will go together the same way. I'm hoping this is ok. If not, can I use a tailpipe expander to enlarge the pipes over the rear to make the mufflers go inside?

Thanks!

Tailpipes normally fit into the muffler outlet, there's nothing wrong with that. In fact, I don't recall ever seeing a regular muffler that didn't have an I.D. nipple on each end.

Thanks Copper. I had a feeling it was ok since it was a perfect fit but since it was not the same as the other fittings, I wanted to check.

I have one other question. The factory exhaust was single with a cat. The cross pipe mounted directly to the manifolds with studs/bolts but the cat was mounted with springs. I know the exhaust is suppposed to have some movement to it but when eliminating the cat and going with duals, do I just bolt directly to the manifolds or do I need springs? The hangers still give it some freedom to move with the engine so I'm thinking I don't need the springs.....let me know.

You don't need the spring-loaded bolts.

didn't think so...thanks! Hoping to finish it all up tomorrow night and start testing things out on Saturday. Thanks for the help!

Moose

can you give me any specs on the kit ie company part number etc. my exhaust is garbage, completly rotted out

Hey Moose!

Here's the link to Classic Exhuast's website:

You have the option of going with standard or stainless, single or dual. I went with standard but upgraded to dual. I was VERY happy with the product and service. Everything arrived at my house within just a few days of placing the order and all of the pipes were marked so it went together pretty easily. He will also sell a hardware set so you'll have everything you need to install it (the only thing it didn't include were the nuts/bolts to mount the lead pipes to the manifolds. You can reuse your old ones or buy new ones at the hardware store...make sure you use anti-seize!)

Let me know if you have any other questions.

PS...The quarter fillers are in the works. Let's hope Ken pulls through with a great product!

Moose

thanks, maybe once i get it running decent i can save up for some new pipes is the alum style aluminized steel? also do they come with the mufflers? can't wait for those rear fillers by the way.

76 Regency

Hey Moose!

I believe they're aluminized steel and I'm very satisfied with the quality of the work they did. They do not come with the mufflers and/or resonators but they do sell them or you can buy them separately. I had ordered mine from Summit. Keep your fingers crossed on the fillers. We all have a lot riding on Ken doing a great job. I'm not sure he realizes how great it will be for him to make them well. He will get a lot of sales for sure!

sounds good i would like to install glasspacks anyways, do they come with any hangers/clamps?

76 Regency

Ha, I guess you like a little more rumble to the exhaust. I like mine nice and quiet. The hardware kit is sold separately but I think it was around $35 or so for the dual exhaust set with all the hangars and clamps. I forget, are you replacing the single or are you going to dual exhaust?

Moose

my car has a mediocre set of duals on it now, but they're so rusted that new pipes and glass packs would actually make it quieter, but first i need to get it running anyways.

76 Regency

Hey Moose,

I didn't know your car wasn't running. What's wrong with it? Can you post some pics? I don't think I've ever seen your 98, have I ?
