The car currently has an old Borla exhaust installed by Lingenfelter back in 1993.
My big round mid-car "resonator" was hit while the car was being backed off of a tow truck by the previous owner. It dented it , and now it rattles like the insides broke apart. Its LOUD like a catalytic converter heat shield making contact with metal somewhere. Are these straight-through mufflers like the magnaflows? If so, can I just replace it with a straight-through magnaflow muffler? This is the big muffler in the center, before the two smaller ones at the rear by the tips. It looks like it has both pipes from the headers entering it on either side, then exiting it on either side. ![]() Thanks for the advice , thanks ![]()

I have a spare Corsa resonator that you could plumb in there. Any exhaust shop worth its salt could make it fit. Is the exhaust 2.5 ot 3.0 ?

Its 2.75 Challenge exhaust, take the resonator out, it necks down to 2-2.25 inches and cost you HP, out an Xpipe in place of it.
You will pick up 5-10hp

I wouldn't waste money on an X pipe to fit the Borla. Go with a newer system if you've got the cash, or have a muffler shop remove the resonator and replace with two straight pipes until you find a system you like. I went from the Borla to a stainless 3" B&B system with X pipe, and it's not for the faint of heart, (meaning wives ![]() ![]() Also, if you're looking for a system that isn't too loud, but really flows well, search for the link to Hib Halverson's article on how he built a custom one with many stock parts that flows really well. Anybody have that link?

Custom built x-pipe in place of the resonator?

Dump the Borla! Get an Xpipe to replace the resonator, then do DynoMax Ultra Flow or even the VT muffs for drone control.
