not on the cupra, but used to have a grp n exhaust on my 106 gti, sounded the absolute nuts proper raspy. kicked flames out on gear changes
Yeah it wouldn't have been the exhaust giving flames, it would be the unburnt fuel igniting off the heat, so wouldn't have thought it should flame unless being driven seriously hard!
yes it would, driving it hard. the system is less restricted take off an exhaust from the down pipe and then run it youll be amazed how much flames are produced.
I had a 2001 106 GTi and I fitted the stainless group N exhaust with dummy cat (made by Scorpion for Peugeot) and a ecosse air filter. Apart from those bits the car was standard, it used to pop small flames out the back on the over run. It was very loud though, sold it in the end and put the original exhaust back on, which killed the mid range in comparison.
Fair enough, if it did... it did I stand corrected.
