Default Initial Feedback on my experience

I purchased off Ebay for less than $250, and I couldn't be happier with them.

Build quality is excellent, and fitment was perfect. Bolted right up to stock US spec Section 1. I ended up re-using my stock hardware for the header to S1 flanges.

I'm running stock US spec sections and muffler and it sounds great. The perfect amount of rasp and deep growl. I was considering getting a catted S1, but not now after actually hearing it run.

Default Re: Megan Racing Headers

So anyone experience an intermittent exhaust leak on these headers only after the car is warmed up and only with the car is certain loads (like braking). I have noises that might actually be an exhaust leak and I am wondering if it the headers here. I did use OE gaskets on the install. I had a leak from the EGT but then fixed that. This noise is the only one i hear now.

Nope - used OE everything, and I've had issues keeping the EGT wires from melting with their odd bung placement, but no leaks
