Senna117 3 Posted May 21, 2019 Hi guys I own a 76 XC, It has a stock 4.1L straight-6. Ive had it for 2 years and have enjoyed it but feel like i need a bit more noise and power now, can someone give me a point in the right direction on where to look for extractors, websites, brands, tips, really anything. Thank you 1 macman reacted to this Share this post Link to post Share on other sites
deankxf 20,336 Posted May 21, 2019 for Me, on stock engine's i wouldn't even bother fitting extractors. just fit a bigger exhaust with sports muffler. one of the best crossflows i heard was still running the manifold with the pipe stepped up to 2.5" and ran with one straight through muffler. you'll probably find it will lose bottom end power with the bigger exhaust, so maybe try just a 2 inch straight through muffler first(cheap also) 1 matt_lamb_160 reacted to this Share this post Link to post Share on other sites
Senna117 3 Posted May 21, 2019 I feel like a whole new exhaust and muffler will cost a bit too much for what I want, I don't want to ruin the cars originality too much and with the extractors it will be bolt on and off quickly if i want to swap back, if its not enough i can buy a little muffler afterwards, can you recommend any brands? I've seen "Pacemakers", "Tiger Headers" and "Hurricane headers". Share this post Link to post Share on other sites
deankxf 20,336 Posted May 21, 2019 in My opinion extractors make no difference to exhaust sound other than you can hear more engine noise at the front. a sports muffler replacing the current one will be $100 fitted. cheaper than any extractors and your starter motor and accelerator cable etc doesn't get cooked(extractors get hot) otherwise, wait for more replies, but if you only want it to sound better, that's what i'd do. (it won't go any better just by fitting extractors.. the manifold isn't a restriction on a standard engine) 1 matt_lamb_160 reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted May 21, 2019 All of those brands are good, but don't expect the stock paint finish to last more than a few months. Not a problem if you don't care too much about appearance.On a stocker, I would go with a 6-2-1 design, which joins 1,2 & 3 in one group and 4,5 & 6 in the other. This configuration is also easier to fit and clears everything by a more reasonable distance than the other design, which is 6-3-1. This is a more racey design that pairs 1 & 6, 2 & 5, 3 & 4 together then merges each of the 3 pairs for 360° pulse tuning. This is a higher rpm design. These extractors are generally more expensive too.Pacemaker makes both kinds, not sure about the other brands.Sent from my CPH1903 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,357 Posted May 22, 2019 its hard to go past pacemakers i fitted them on my engine and come with correct gasket,bolts,and bolt on flange,for $400 its worth it,i run a 2 1/2 exhaust with stainless muffler straight thru,all up was $850. Share this post Link to post Share on other sites
Senna117 3 Posted May 22, 2019 Thanks guys, @CHESTNUTXE is yours a 6-2-1 design for the stock motor? My piping is 1.8 inches all through and dont think 230km motor would work well with a 2 1/2 exhaust. I would just like the extractors for a bit bigger piping plus mine is 6-1 would be interesting to see with bigger pipes and 6-2-1. May as well get the pacemakers just wanted something more and cant go past all the positive comments. Thank you @deankdx its my 1st time doing an exhaust and like to learn from experience, ill let you know if the extractors change the sound at the back 1 deankxf reacted to this Share this post Link to post Share on other sites

Senna117 3 Posted May 22, 2019 I just ran into a problem, my bolts dont line up with what the pacemakers ph4470 are. They say it fits XC but it doesnt look like it, is this what you purchased? 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,357 Posted May 22, 2019 opps i forgot yee had a iron head,just go a xc set on e bay there is many that suit xc,very cheap too around $200 Share this post Link to post Share on other sites
Senna117 3 Posted May 22, 2019 Looking at it i believe it may actually fit i believe i only need the top right hole and the bottom left gap they've got open. I think having all the holes are for other models. Did you have to cut or modify yours at all? @CHESTNUTXE Share this post Link to post Share on other sites

[mention=7196]CHESTNUTXE[/mention]They should have 2 sets of holes on the header flange why not just ring and find out but no no mods just bolt on and lay down a rubber roadSent from my SM-G570Y using Tapatalk 1 1 gerg and Senna117 reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted May 22, 2019 2-1/2" is no big deal. Exhausts are a semi-consumable item so if/when someone wants to buy your car later down the track, originality in that regard isn't an issue as long as you don't go stupid with a 3" staino system and fart can out the back. As long as you go subtle with a decent turbo muffler in the standard place and the whole lot looks like it should be there, that's what you should aim for.Sent from my CPH1903 using Tapatalk Share this post Link to post Share on other sites

I think having all the holes are for other models. Did you have to cut or modify yours at all? @CHESTNUTXE That's how mine look on my iron head crossflow too, just some of those bolt holes don't get used. Looks crap IMO but I believe that's just how they are. Extractors and larger exhaust are the generic first upgrades and obviously will make it louder. But whether you like louder or not is a matter of personal preference. Previous owner put extractors and a single 2.5" exhaust (with a 3" tailpipe section) on my 250 and I actually almost hate it. He absolutely loved the sound, but it gives me a ringing headache. Just two opposite ends of the scale with what some people like and others don't like. 2% of the time I get a bit of enjoyment when coasting down hill in 3rd gear, it sounds alight. But otherwise it's just loud. Power-wise, I don't know what it was like before the extractors and exhaust, but it hasn't got much guts now, so I hope it wasn't worse before - my suspicion is it's the same, just louder. P.S. I love your XC, looks great! Share this post Link to post Share on other sites

Some people enjoy the ear rape but theres an art to it, i like the sound of mine but want a BIT more noise so im hoping extractors will do it. I rang around and it will fit on but need to take it to a shop to get the 2 1/2 outlet taken down to i believe mine is around 1.8 inches. Might not follow through with the extractors as im told its a permanent modification and the old cant be put back on Share this post Link to post Share on other sites
Thom 6,654 Posted May 22, 2019 I thought my xflow sounded ok, it had a generic set of extractors with a 2.25 inch exhaust a straight through muffler and a resonator here's the same setup in 2 different cars, when the engine went from my xe to the xp it used the extrctors and the whole exhaust system of the xe (with 1 bend modified to suit the xp) Share this post Link to post Share on other sites

Ill give you 100-120 which takes twice as long yeah it does depend if the pipes align, they sometimes need a bit of an S shape bend in the pipe to line up(this takes a competent exhaust shop like 10-15 mins all up) 100-120 would have to be quicker than My diesel cars here(diesel mazda van barely gets to 120, actually i think i saw 118 on the GPS once.. the diesel gemini can go much faster... takes a while though) 1 Senna117 reacted to this Share this post Link to post Share on other sites
