It's that time of the year where I want to mod my car again.

Right now, I've been trying to really indecisive of should I buy the Weapon R Headers + Testpipe combo (which runs for aorund $650?), or would running TopSpeed Headers + Any Test pipe would almost has effective?

The reason so, is because I'm actually have a fabricator weld me a catback to muffler, and I know for a fact having him weld me a header would take forever and be expensive.
I've seen dyno's of the Weapon R combo, some were able to obtain 14-20whp. I couldn't find exactly what a TopSpeed Header + a Testpipe would yield? ( is that even possible, in addition to the flexpipe?)

I would like to get some feedback, because I know for a fact I would be able to save at least around $300 if I go for the TopSpeed + Testpipe.

But gains wise also might change my mind.


Thanks.
