Default Muffler only replacement

My 89 has stock pipes and mufflers, while it does sound nice, I really want MyLilSlut to growl at me, especially when I jump on the gas pedal. Is it possible to replace the mufflers and get what I'm wanting? If that is the case and I think it is, in some of you alls experience and opinions what muffler would do me the best?

Thanks
Robin

your stock mufflers only had one working outlet. Go to dual outlet muffs or muffler eliminators for more sound. I have OEM style dual outlet Magnaflows on mine. try www.corvettecentral.com for a wide selection.

Badduck, I'm not real savvy about this yet, but trying to learn so I can make the best decision for what I want and what I want to spend.

When you refer to the working outlet, that is part of the actual muffler itself and dual outlet muffs or eliminators will work with the stock pipes?

It's the outlet on the muffler itself. If you start your car and put your hand near your muffler outlets you will feel exhaust from only one of those outlets on each muffler. (Assuming you still have the original mufflers). On dual working outlets both have exhaust.

makes sense, I will check that out, now I am assuming it is the stock setup and I may be wrong about that as well.

I put these guys on my car:

http://www.summitracing.com/search/?...LK-17483&dds=1

Summit was much cheaper than the usual Corvette suppliers.

They claim they're exactly the same as the stock mufflers internally. The main differences are that both holes are open and stainless steel tips (look very nice after polishing). They are definitely louder than stock.
