Default Corvette Central Muffler Eliminators

how do these go on? do i have to cut my stock exhaust or can just clamp these on? rear part only. Also can having no to verylittle back pressure affect the engine in a negative way? i.e. valve damage, lack of power, etc?

thanks!

They're supposed to replace the muffler. Just take the mufflers off and clamp them in place. The stock mufflers don't have all that much back pressure either, you probably won't notice much difference, maybe a little more sound.

what year? I believe that 92's and later require cutting.

Fill out your sig with your vehicle info.

My Right one cracked and fell off the other day. It was ok as the thing fell off when I was pulling out the system for maintenance on the Tranny.

I threw the muffler in the back for when I had a chance to go to my Muffler shop:

Fantasy Muffler-Buena Park...best muffler shop in all Orange County

Anyway....really there was no difference with that portion of the exhaust off or on.

Now with the Headers open, that was whole different sound all together.......LOL

No back pressure is a good thing for an engine. Getting the exhaust pulses timed correctly can affect torque/horsepower output, but will not hurt the engine itself. Put them on and let it breathe!

I think on these Corvettes the catalytic converter does most of the muffling. Take it off and it sounds like an old Chevy V8 which is good.

I had a local muffler shop make a set for me for under $100 total. The advantage here is that you will save money and get a better fit that a bolt on kit out of a box from the catalogs.

The price included the chrome tips of my choice plus the pipe and labor. A reputable shop will have a decent selection of either chrome or stainless eliminator tips in different styles. Took maybe 20 minutes for the entire job.

When my 92 was mostly stock I put on a set of elims. Had them fabricated at a muffler shop, and picked out a nice set of chrome tips. When I installed long tube headers and RT hi-flow cats, I had to go back to the stock mufflers - the sound became unbearable. It sounded like a broken truck!

As some have mentioned it is loud. I blew out my mic on my digi camera when I did my first burnout.

Anyone here with eliminators gone from a working cat to a gutted cat with them? How much did the sound change with just that?

After the rest of the exhaust has been removed the cats are the last line of defense for sound reduction. Remove those and it sounds like a race car on acceleration. It does get loud.
