In this pic it looks like the silicone coupler is overlapping the MAF location in the tube, not sealing fully. May be the angle of the pic too but the blocking plate doesn't look quite flush? Could it have been a vac leak there maybe
Summit have the MR133 available. Can't 100% confirm they fit though. If I were in the US I would've taken the chance and bought them to test, but since I'm in aus I didn't want double international shipping lol
When you loaded the flex tune and started the car up, was the car already warm or was it a cold start?
I had an issue once on my 16 where I went from E85R to flex, and then did a cold start. Because it was on E85 it didn't want to start first time (ambient temp was cold), so it stalled and that...
Why the aversion to taking the rear seats out? It's 3 bolts, takes 5 minutes to do. Takes me 15 minutes to do passenger and rears.
Sounds cool though, interested to see results. Did you ever run the car at the track with the ported 18 mani?
I'm using Motegi MR135 17x9.5+45, I bought the tyres off ebay. I think the tyres came from Rocket Industries but can't remember exactly. Wheels I ordered from Showster, they had to order them from the states. The setup cost me $1150
Depends if it meets up to the catback, or if it's too short (which most headers are unless they have the direct connect extensions). If it's too short then you can just have some additional pipe slip onto the connection pipe but bolt on to the catback - like a collector extension
Haha all good. I've done the opposite, bought xforce headers to mate up to my Corsa x pipe. Definitely prepared to hack the connection pipe from the headers though, seems easiest to cut and clamp some additional 3" pipe.
If you're not prepared to hack then I'd just take it to an exhaust shop...
