I fitted my Eternal exhaust on Saturday and thought I'd share my experiences.
Ordering was tricky. When I called them on the phone they insisted I order through eBay which would have been OK, except it is not clear which parts I needed. The centre sections were not labelled left and right so they emailed me eBay item numbers for the 3 sections and 3 fitting kits. You then have to 'buy' 6 seperate items but not pay for them otherwise you will pay too much postage. You have to buy first but not complete, requesting a shipping price. All a bit complicated but I got there. £133 and some change delivered.
The system arrived 3 days later. All the right bits were there.
Getting my old OEM exhaust off was a nighmare. I had to dremmel through 3 of the 4 studs on the cats and then drill out new fixing holes.
The new left hand section went on OK and fitted nicely. But the right hand section was tight. It looks like the hanger was too short so I had to pull down hard to make it fit the cat.
When it was all assembled, the tailpipe looked 3 inches too short. Measuring my old end exhaust section I could see it was. So I took a hacksaw and cut off the end section of my old tailpipe, used an angle grinder to cut two slots in it and slipped it on the end of the new tailpipe. Finally I secured it with a U clamp.
Had I known, I would have saved myself £16 and not bothered with a fitting kit for each section. My old rubber hangers would have been fine, the bolts for fitting to the cats come without nuts and washers anyway and you end up with 4 U clamps when you should only need 2. So save yourself some money and buy 2 U clamps and 4 bolts seperately.
Despite these minor irritations, I'm really pleased with it. It is nice and quiet with no booming of the cheaper Kwik-Fit type systems I had once before. So it's a recommendation for Eternal from me.
