    Cat Back Exhaust Systems Mk4 1.6 16v

    Hello, I have a Peco Boxer back box on my Astra G 1.6 16 valve, if I bought the rest of the system (cat back) would it be better or worse for my car ie engine? As some one a while back said some thing about it damaging your engine if you get a full system, any info would be great and save me some money in the long run. Cheers. Mark

    who ever told you that fitting a CAT back exhaust will damage the engine is obviously a cycle lover!!!!

    the more gas you can get out your butt, the better you feel right???? Keep the gas in and you get stomach pains!

    Its the same wiv ya mota!!!!

    Cat back will be loud, but will certainly free up the engines breathing!

    If this is going to be your only mod, I would not worry about getting the ECU done, if you have done other mods, or have near furture ones in mind, leave the ECU until then.

    The only possible thing i can think of would be your engine managment light coming on, but this shouldnt happen with a CAT back system

    Cheers for the info mate, on the old forum board some one with a modded Coupe said something about cat back exhausts and it put me off so I just wanted to know for sure , I will buy one now , I have an piper cross cone filter on my Astra so I won't need to re map my ecu. Mark

    Got a magnex cat-back on mine and no problems at all with the ecu or management light, its not even that loud which in a way was dissapointing. Did help performance a bit tho!

    I was going to buy a cat back system for my car yesterday but Halfords said they don't do them ? I thought when I bought my back box I had the option to buy a full cat back system at that time? Do Peco do a cat back system. Mark

    Most exhausts manufacturers do offer the choice of just back box or full system, not sure about halfords never really shop their for performance parts. Try WRC or Revolution, or even Monty at TFG should probably be able to source you something out.

    Yeah that was mine, parked on the kerb bit, did you drive round a couple of times then go into Mcd's? Should have gone to PV2003 was really good! Before you go to TFG read Demon Tweeks as they mainly supply their parts, if they cant offer you anything try WRC, really decent bunch of lads and will find anything you want, can get all the Regal stuff aswell.

    Their was an astra G at PV with a dual exit Peco system, which I think was a full system from what I could see, so Peco must do one, im after a dual exit for mine as the magnex is too quiet!
