First Gen Exhaust

[CHEV 383]

Over the winter, I bought some new headers from CS3 and they do not line up with my old exhaust. Good reason to upgrade exhaust.

Right now I am running long tube headers, into 3 inch exhaust pipes. they run straight to the back, over the axle, and into a stock type transverse muffler, and then dump behind the rear wheels, in stock type position.

Poll Options:

1) Leave as is, and just fix attachment to new header outlet location (a few inches or more)

2) Replace pipe and muffler with new transverse muffler.

3) Replace pipe and muffler with dual mufflers in front of the axle, same outlet location.

4) Replace pipe and muffler with X-Pipe / H-Pipe and dual mufflers in front of the axle, same outlet location.

The only thing I am worried about with options 3 & 4 is ground clearance. There ain't a whole lot under the car. Suggestions on brand of dual mufflers to install??

With Option #4, I don't think I would be able to drop tranny with an x / h pipe underneath. Does anyone have any other solutions??

Thanks for your opinions and suggestions!!!

If it helps i have long tube headers, straight pipe into some flowmaster mufflers and that it. Its true duals all the way back!

Its Easy to spend your money #4

But if you are happy with your old sound and performance fix the old.

I have flowmaster delta 40s on mine (small block) The hole kit you can get form summit.

^ Yep...x2...get the x-pipe as close to the headers as you can.

If you want to try something different (at least not that I've seen), instead of mufflers, run stocker 78-81 resonators (smaller package...easier to work around)...should be a cheap alternative to a nice quiet cruising speed until you open it up...

The last option.

Might as well do it all.

If you want to save money, do #1.
If you want a real nice exhaust that you will never need to replace, look at the magnaflow. Stainless steel and a x pipe. Send me a pm on the Magnaflow if you think you might like it. Its not that much more than a Flowmaster. I can actually help you anyway you decided to go.

i have the same kit as Les and have gotten a lot of compliments - however....

if i were to do it again id likely do it similar to jeffs suggestion but go with long tube resonators (hollow guts) they sound really mean all the time

it really depends on the sound you want

...or, just run open headers.

Costs less!

you need some back pressure though

he is the man with the plan

You should take a look at Pypes Exhaust. I have the stainless, X-pipe, transverse muffler system on my '74 Z28 and it's awesome. Quality, fit and finish is first rate, installation is pretty easy.

What is the sound like for that system? I have been looking at MagnaFlows, but am intrigued by the Pypes website. The systems look good. I can't hear the sound clips from work, so I will check them out at home this weekend.

I can only speak about the system on my car. It's the "standard" X pipe with transverse muffler for a 2nd Gen. There are optional mufflers that are louder and probably sound different, and of course the two smaller muffler, under the car system probably sounds different still.

But the system on my car sounds different than any other exhaust I've heard. It's definitely not a Flowmaster type sound. It sounds nice at idle, but is not an exceptionally deep sound. My back garage is probably 50 feet from the house, and even though the idle sound isn't loud standing next to the car, it has a frequency that penetrates and can be heard in the house. Not in a bad way, but you know when the car is running.

During acceleration, it's louder and has what can be described as a "modern" sound, more hi-tech than a traditional turbo muffler or glass pack setup. Sort of a tearing of a bed sheet, raspy, ripping sound. Everyone that's hears it says they like the sound, but it does not sound like any other system they've heard.

Sound is subjective, and my description probably is not much help. I like the way it sounds. Hopefully you can hear the sound clips on your home computer.

Many 2nd Gen owners on NastyZ28.com are running the Pypes system, and when someone makes a post asking about exhaust, the Pypes system always comes with many recommendations.

I wanted the transverse muffler for ground clearance since my car is lowered. The transverse muffler is different that the stock muffler in the way the exhaust runs through it. A stock muffler has the exhaust pipes both entering the muffler across from each other and the tail pipes doing the same, causing the muffler to be sort of a mixing chamber. The Pypes transverse muffler has the tail pipe exit across from it's corresponding exhaust pipe, effectively making it two straight through mufflers packaged in one can. They claim a significant increase in flow over a traditional transverse muffler. Seemed like a great idea to me.

Thanks for the description. It can be difficult to explain sound. I suppose the best thing would for us to get together at the big Meet and look at your car. When my engine builder was working on the motor, he warned me that the "cork" in the rear of my car was going to limit all the money I spent on my motor. I think your description is accurate, as to the stock muffler. I like the design of the transverse Pypes muffler.

Thanks and hopefully we can get together at the MEET.
