Tune after Headers only?

What's the difference between early and late cat delete pipes?

Thanks Dave I will zip over and review. I had dropped this idea a long long time ago have thought I needed Euro 3.2 manifolds. Hard to come by over here. I still have the dead octopi (stock catted headers) strapped under there. I am afraid of losing bottom end torque as it a street drive car. I am considering the FVD headers and mid-cats (TBD) as the fitment may be less of a risk.....how your bottom end with this set up?

Agreed with edc - nothing but positive gains. Notably better 'revability' in the lower gears. My Circuit Works mid pipes did require a bit of a hammer dent on one side's tube for rear axle suspension clearance, but they fit fine on the other side. Which plays back to some of my earlier comments about aftermarket exhaust pipework fitment being a hit or miss deal. But once the offending tube was massaged a bit, all ended well, and I'd never consider going back to the OEM setup.

For the very cheap purchase cost of a set of used USA-spec early non-cat manifolds like mine, I'd urge you to just try them and see how you like them.

True, good point. if I do come across them I will grab them. Fitment issues are why I was considering these

The thinking was pay for pieces that will fit but don’t break the bank. Anybody try these?

Sorry for bumping an old thread but this was the only relevant mention to this particular header I could find on the forum.

I purchased these a few months ago and will be installing them next week. I would also like to know if anybody has taken the plunge on this set of headers.

They are very lightweight and beautifully welded, so I am looking forward to the result, but not particularly happy about the loss of the primary catalytic converter when removing the factory header.

I almost purchased a set of these a few months back, my car is euro spec should be a bolt in change I would think. Looking forward to your report, I have the brombacher muffler and very pleased.

The eBay manifolds/headers work great for a fraction of the price of an FVD/Cargraphic etc set. Unless you like spending money and are chasing every last single bhp then I'd seriously look at them. I've had 2 sets over 2 cars and nearly 10 years now. You might need to bend a corner of the undertray a little out the way, make sure the PAS line is not going to foul and check the alu diagonal braces don't get too close but they are are hard to beat for value.
