TTI exhaust, is it worth it??

Sounds like another person with TTI problems lol. As far as headers go i'm going with hooker comp. headers. I've always had good luck with them and so has my dad (big block 69' charger). For being a bit cheaper then some i think that they're pretty good. I pretty much had the system narrowed down to the TTI system or the summit system that's wayyyyy cheaper. mind you though if i spend less money on the system maybe???? i'll be able to afford the TTi headers....maybe???? other then the TTi ones what others do you guys use?? Thanks for the the replies guys it's very much appretiated!!
