EGT Reduction w/4" catback

How much can I expect EGTs to improve with just a cat back 4" (with or without muffler) over the stock setup.

When we tested our cat back systems we saw a drop in EGT's of about 150 -170 degrees for the 4" - this was with the muffler in.

I'm also interested in a cat back system.
MBRP - are your 4" or 5" cat back systems available as straight pipes? ie. without a muffler? All the advertisements I see on-line include a muffler.

Thank you.

All of our systems do include a muffler but you can get a muffler delete if you choose to run without.
