Davsurfa Posted March 9, 2013 Share Posted March 9, 2013 At the moment the config is headers, both cats, then straight pipe, no back box, no middle boxes. This is how it was when I got the car. Would I benefit from fitting a back box?? Apart from reducing the noise would it increase back pressure? By the way its a 97 Sport. Quote Link to comment Share on other sites More sharing options...
Davsurfa Posted March 9, 2013 Author Share Posted March 9, 2013 So having posted the same question on FB I've been offered a 3" H&S style backbox, I'll be collecting it on the 23rd, gotta be worth a try :) 1 Quote Link to comment Share on other sites More sharing options...

FR02 MAK Posted March 14, 2013 Share Posted March 14, 2013 what is the car used for ? if its atrack day car best route would be to remove ur cats and possibly a side exit exhaust no back box resulting in no back pressure aiding quicker release of exhaust gasses if the car is used on road replace your existing cats with a high flow sports cat and and put on that h&s back box to retain /amplify the all important flat 4 burble it's a good compromise for a road /track application (key thing make sure the system is running 3inch mandrel bends throughout to eliminate back pressure and to aid accurate exhaust flow ) I hope this has been helpful 1 Quote Link to comment Share on other sites More sharing options...
