are the mufflers on my 97 sunfire GT straight through or chambered? the system seems tuned fairly well and if i put on some magnaflows(straight-throughs) and loose to much back pressure, you;ll have one pissed off sunfire owner who lost some torque. this is one reason i don't redo the whole exhaust with 2.25 piping. im searching but i can't find any REAL claims(dynos preferably) i've just had bad luck with exhaust systems in the past and i love my car so im being careful
You won't lose anything and the onlything you will gain is noise.
