I have a 91 SL and was thinking about upgrading my exhaust also. from past experience i know flowmaster is a good name and for under $300, i don't thnk there is much of any other choice!
Yes that has been a hugh arguement for a while. They say that the open flowing of the CAT will cut down on your Torque but in some cases it can be false. When you have a tinner pipe ( 2.25 ) going into the CAT ( big and hallow ) and than having that exit out into another tinner pipe ( 2.25 ), it is the Torque you feel when you have all that hallow air in the Gutted Cat trying to squeeze into such small piping compared to the CATS allow body structure. So that is why most of the N/A guys should stick to 2.25 inch piping on there exhust systems.nitroucf said:Talk to Tampa95SL (I think thats the right spelling).......Marshall. His exhaust system sounds sweet plus gave him big time power. however said gutting the catylitic converter means a loss in low end torque is WRONG! His car pulls.
