rodney 17 Posted February 6, 2010 Report Share Posted February 6, 2010 there is a selection in faq of exhausts mate... so have a read on there... Thwn ywa once you are 2.5 and above the rear beam you may have issues. that said you can do it but it does have to be high quality zorst made to order or you can oval it and still get teh same flow. but agin quality build needed..

bungy 2 Posted February 6, 2010 Report Share Posted February 6, 2010 The only criteria really is to buy decent quality stainless ie 314. Go for a decent sidewall aswell 1.5-2.0mm. There will be loads of traders in your area but try googling :"the metal supermarket" Link to post Share on other sites
12vvr 0 Posted February 6, 2010 Report Share Posted February 6, 2010 316 is the grade i would go for, roughly twice as expensive as 304 but will last alot longer, in my line of work all we ever use is 316 and its worth payin the extra for 316 grade for an exhaust if you want it to last Link to post Share on other sites
bungy 2 Posted February 6, 2010 Report Share Posted February 6, 2010 316 will outlive the car if you can live with the cost. Link to post Share on other sites
