Hi, would i see much difference in power gain between a Remus backbox and a Sportex cat back? I know the sportex are known to be quite noisy compaired to the remus but im not to bothered about this but im just not sure how restrictive the stock fiat system is, i have read that the back box is quite restrictive but not sure about the rest? Also im assuming a seicento back box wud fit a cinquecento fine? Cheers, Russ

Tuning Power gains from different exhausts?
Make no assumptions about Cinq and Sei exhausts being interchangeable!
Any decent aftermarket exhaust should be better than the standard one, but I'm pretty sure the main improvement will come from the manifold.

ive got a 3 inch sportex system on my sei, not sure if it made it go any faster as my dad had it installed when he has it, but it sounds very nice, not loud, cant hear it in the car, jus when you got your windows down on narrow streets sounds loads better then the chavmobiles with massive exhausts on. alot cheaper then the replacement fiat ones as well.
Thanks for the info guys. Do you think this would fit a cinquecento? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=290378342374&ssPageName=STRK:MEWAX:IT

I'd suspect not (or they'd have advertised it as such). Can't see it fitting an 899 Sei, either. Could probably be modded to suit, but..............
Sportex isnt as loud on a sei as it is on a cinq
Only backboxes are interchangeable between the two, its gets a bit different from there on in, they can be changed and swapped, but it isnt as straightforward as you would think
The exhaust route beyond the manifold is different
The sportex system isnt stainless steel or wasnt, so it would need to be replaced at some point. Dont know about the other
You will see very little gain unless you have sorted out the induction or have other mods as well so if you havent got any other mods then it doesnt matter which you get as the increase will be 1bhp if lucky

I think my favourite for the Cinq is Janspeed. They do come up s/h from time to time and -- as they're stainless and beautifully made -- tend to outlast the cars.
The MPI Sei exhausts are different from the Cinq (and early Sei). It's partly about where the cat is. But the exhausts themselves differ in the bends.

You say the back boxes are interchangeable? So this: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=120502622683&ssPageName=STRK:MEWAX:IT should fit? Correct?
The only reason i ask is that i notice the pipe coming out the back of the backbox is very short and other backbox's i have seen seem to consist of half the exhaust system?
Sorry for the all the questions but i really am stumped on this. haha
Thankyou.

yeah it would fit you would have to modify it and possibly weld it onto your existing cinq exhaust, however as its not for your car it wont be set up for your cars system so you might not see any gains and even possibly loose power
Theres nothing to be stumped about - buy an exhaust thats for a cinq. Simple

The other ones are catbacks (literally, from the catalyst back). Best bet is go see it.
Just avoid the sportex on a cinq unless you always travel above 70 MPH or below 30MPH
Exhausts do make a difference I saw a huge gain on my last Cinq with a custom system but there again it did cost more than a complete Cinq would cost these days.

After looking around at the back box's for the cinq and lookin at the price of a decent one (janspeed or remus) i have decided to go to MIJ performance as there price to fabricate a custom backbox in stainless steel for the cinqucento is £140 (or £200 for the cat-back)! Which i think is great as i really want a twin dtm style exhaust and can only find them in centre exit form (which im not a fan of). Thanks for all the help in making my decision guys.
But that was on a tub, where conventional exhaust logic goes completely out of the window. Any fool can design an exhaust for a turbo (and many have): designing one for a NA car takes a lot more.
second mention this week, cant recommend them enough and i am three hours from their place
