inferno 1 Posted September 2, 2006 (edited) my downpipe has no split in it like the normal mi6 ones, would this be causing my dip in power low down and giving me a higher top end? if so id like a new exhaust please! also would a 4/2/1 be significantly better than a standard mi manifold and downpipe?

Ahl 4 Posted September 2, 2006 In theory that would be the case, but it might not be the only cause of your problems. It probably doesn't have *that* much effect. It also is a 4-2-1 system as standard with the split in the downpipe and has shown to flow very well for a standard system. Personally I wouldn't worry about fitting a better manifold until the car was putting out closer to 200hp. Share this post Link to post Share on other sites
welshpug 1,657 Posted September 2, 2006 i'd second that, leave the std manifold well alone but get a split downpipe to suit, the Mi16 has a bad enough flat spot in power mid range as it is! Share this post Link to post Share on other sites
maturin23 10 Posted September 2, 2006 I bought an Alvin downpipe this morning from Partco for £35 + VAT Got the split - looks well put together. I also got a carrier bag of nice wide new jubilee clips of assorted sizes (probably about 30 odd) for free Share this post Link to post Share on other sites
