Bourkey Posted April 2, 2008 Share Posted April 2, 2008 Hi all,It is nearly 2 am and i just had a quick brain wave (you can be the judge) about an exhaust system. I was wondering is there any restrictions on side exit exhausts. Like at MOT time?The theory is that i want a new exhaust when i get my engine in but i also want a decat as well. I've always fancied a front side exit but never really mentioned it.Also how loud is it? Will it always have flames? (not too fussed but would be cool every now and then)? Finally which side do you think i should get it on? Id have a back box (front box) not a simple pipe work system as i wouldn't want it mega loud.Thanks in advance.Please also put pics up as i cant find many.Bourkey Quote Link to post Share on other sites
cheezeitthedog Posted April 2, 2008 Share Posted April 2, 2008 Duno how it would look on a starlet as Ive never seen anything like that. Sounds interesting though. The only thing I will say is if you end up going rear exit I know the entire body of the piping has to be concealed. I know someone did a rear side exit with an Impreza and found you couldnt make it outside the body work like the old AC Cobras because of MOT restrictions.Flames really depend on your car and I guess to a degree also the structure of piping you go for. And flames will generally only kick if you rev it. You shouldnt really be spitting flames when youre sitting in traffic or anything lol. Quote Link to post Share on other sites
Idrees Posted April 2, 2008 Share Posted April 2, 2008 Think about your catalytic converter too. Would you use the stock downpipe on the 4EFTE? Quote Link to post Share on other sites
StarletRick Posted April 2, 2008 Share Posted April 2, 2008 it isnt illegal to have a side exit at all, unless it sticks out firther than the extremities of the car, ie, the wing mirrors. all you have to do is watch the noise. lots of starlets have side exits. i was thinking about getting one for mine made up as it wouldnt be that much aggro.

cheezeitthedog Posted April 2, 2008 Share Posted April 2, 2008 There are lots? Any pictures? Gotta say Ive never seen one lol Quote Link to post Share on other sites
StarletRick Posted April 2, 2008 Share Posted April 2, 2008 abbott has one, montana has one, dave has one. ive seen a few more on cars i dont know aswell. Quote Link to post Share on other sites
montanajr Posted April 2, 2008 Share Posted April 2, 2008 They cut the bottom off my Japspeed de-cat, welded in a bend and then a straight 2.5" pipe to a tanabe back box. Its actually not that loud on idle, but when you go for it all hell breaks lose. Cost me £90 to get made plus £40 for the backbox. I lurve it. Quote Link to post Share on other sites
Bourkey Posted April 2, 2008 Author Share Posted April 2, 2008 The idea is beginning to grow on me now. I doubt id get pulled over more than i already do anyway. They have a thing about modified cars in my area. They just pull you over to check its the correct person driving and if your speeding of course. I've never seen it on an N/A bodied car (except when Alex did it for a laugh once) so im hoping it will look right.@ Montanajr - Does that not get hot and melt the bumper?? Looks really smart that though.Bourkey Quote Link to post Share on other sites
RobSR Posted April 2, 2008 Share Posted April 2, 2008 also come MOT time your car is going to be a hard one...its an UK car which means it has to have a cat, even though the engine, is jap....Rob Quote Link to post Share on other sites
Bourkey Posted April 2, 2008 Author Share Posted April 2, 2008 Your right about that i think but i'll have a standard exhaust spare anyway if i have to change it over.Bourkey Quote Link to post Share on other sites
montanajr Posted April 2, 2008 Share Posted April 2, 2008 Has slightly burnt the bumper but only on one side, not as bad as I thought. I have my MOT tomorrow at 11am, so I should hopefully get through fine! I'll letya know! Quote Link to post Share on other sites
pallett Posted April 2, 2008 Share Posted April 2, 2008 i quite liek the idea of a front exit aswell on my n/a, but could you run one still using the standard cat? actually im gonna go downt o local exhaust place and find out, as it works out cheaper than a full system and means the back end of the car can end up loweer haha Quote Link to post Share on other sites
nic1.3 Posted April 2, 2008 Share Posted April 2, 2008 i guess the oem cat could be included when its being built but if your going that far why not go for a high performance cat and be done with it....also even with a cat of sum sort would it pass emissions for the ukdm starlets Quote Link to post Share on other sites
pallett Posted April 2, 2008 Share Posted April 2, 2008 cant see why it shouldnt pass MOT unless it is ridiculously loud, or sticking out wayyyy to far or something,. Quote Link to post Share on other sites
RobSR Posted April 2, 2008 Share Posted April 2, 2008 you wont be able to have the cat in the stock posistion, it will have to be somewhere else obviously...get it made up, so you can bolt it in and out...so put the cat in for MOT, then after you have passed..unbolt it, and replace with a straight bit of pipe..i.e Decat...

MaccyD Posted April 2, 2008 Share Posted April 2, 2008 pallett, a side exit on an n/a would be pointless, it would do nothing but lose power as you would have no back pressure in the system plus it would be deafening. Quote Link to post Share on other sites
Bourkey Posted April 5, 2008 Author Share Posted April 5, 2008 @montanajr - How did your MOT go with your exhaust????Bourkey Quote Link to post Share on other sites
montanajr Posted April 5, 2008 Share Posted April 5, 2008 Failed.1) Had no rear fog.2) Had no bracket holding silencer to chassis.3hours later after wiring in a fog, arguing with my dad 'because I told him I needed a rear fog (he disagreed! rofl) and searching for the biggest U-Bolt known to man, I went back and passed. The guy had no problems with it being a front exit, couldn't care less. But all mine has is a bracket from piping to block, and he said that in all cars they have atleast 1 or 2 rear silencer hangers holding the silencer to the car. He said from a safety point of view, if the welds were to break, the silencer would come lose straight away and drop onto the floor. I would either run over it or someone else, which would be dangerous. So I put a huge U-Bolt around the silencer, made up a bracket that bolted to the chassis and that was that. Fair enough I guess. No other advisorys either Lovely stuff. Quote Link to post Share on other sites
