Want to know what else everyone else see's as the pro's and con's of a full titanium exhaust versus a less expensive stainless exhaust. I have been planning on a Apex'i N1 Ti for my new EVO IX MR, but if I wanted to be cost effective is a second approach better? Let's say instead going with the Stainless steel N1 or GT spec exhaust, and spending the extra money saved on a least a downpipe and possibly a high-flow cat. I would say the latter would gain more hp, but obviously weigh more by about 20 or 30 lbs. So is the weight savings better, or the extra hp from a more free flowing exhaust system?

 

There's really nothing to ask. One costs a crapload more than the other, and the only gain is a few pounds...not 20-30 lbs. SS exhausts are much lighter than stock, too, just not as light as a Titanium. The power is the same either way.

You can spend $799 on a titanium cat-back, or you can spend $600 on a full MEgan TBE, then spend the other $200 on a mail-in flash or MBC + gauge. That's 30-40whp instead of 15whp for the same cost.
