380 for used ofh, 500 for oft. Add e85 and I now have a better car for under a grand. No carbon fiber lightweight or ecu tricking bullshit. Just 30 or so more horsepower and a torque curve that is satisfying.

A. I said header and OFT.
B. You guys are talking about full exhausts not just a header
C. You only get big gains with e85, not pump gas

Add those things together and you are in way more than 1k and also at a point where you have to fill up at special locations and hope there are some nearby you.

There are multiple dynos showing that just the header and OFT only net you 5more hp up top and make the torgue dip less (sure you get more than a 5hp gain in the dip area).

A slight increase in PEAK hp does not tell the whole story. Increasing the AREA under the torque curve, especially in the rpm range that you are typically in can make a significant difference in how the car feels.

Here’s a thread with OFT+OFH on pump gas. Pretty good gains on the top end!

I've got flex fuel and catless exhaust (exc. stock overpipe) and I'm in for less than $750...

It's all about how much stuff you can do yourself.

yep, and finding good deals.

used oft was 380, CNT UEL V2 was 300, used invidia resonated front pipe was 100, traded my factory borla axleback for a tanabe concept g. gaskets were less than $50. ill still be under 1000 after adding a overpipe.

Only 5hp? I had an OFT and I agree that up top it wasn't very impressive. However, I had the stock exhaust manifold.

Go with catless and if you can have e85 available go for it and report back

For me, the car feels just right now. Not a rocket but enough for daily driving. Especially in midrange.
