I recently had a 3in custom apex-i exhaust made for my 02 type s, then had them dyno the car too, with the exhaust it made 175whp and 126tq do these numbers sound typical? thanks

 

did you do a run before installing the exhaust? dynos vary from one another and so do testing circumstances. if you're making 175 whp i'd say thats pretty good for an 02 with a 3" exhaust. i've seen dyno slips from 02-04 models making betweeen 160-165 stock.
