Im curious if any of our members have done thier exhaust yet. I was thinking when my car arrives to just replace the original mufflers with Flowmaster. Is that worth it ? will I gain any performance ? Had anyone seen hi flow cats for this car yet ? Am I best off going with a total cat back or is replacing the mufflers good enough ? The borla system seems a bit pricey but if its the concensus that a system like that is the way to go then Im going to save my money for a while. any input is appreciated :black5thburn: any suggestions ?
