Exhaust system upgrade question
Hey all,
I'm considering my options on upgrading my stock '03 CL-S exhaust. Can anybody break down the approximate HP/torque gains that each component of the Comptech exhaust system will give?
-Headers: ?
-B-pipe: ?
-Axle-back: ?
If I only do the headers first, will I get a nice performance improvement or will the stock exhaust hinder the impact of the Comptech headers? If I do the B-pipe after the headers, and leave the stock mufflers for now, will I get even better air flow (than with just upgrading headers) even thought I've not changed the mufflers back yet?
I've heard on these forums that the axle-back exhaust gives the least HP gain (1-3 HP), so it seems to me that this component should be the last thing upgraded. Does this make sense?
Thanks for any help!
Brian
