Not a super tight budget but if I dont need to do it id rather spend it on something else!Looking to reach 380rwkwApologies if this is somewhere else on the forum..Dave Link to comment Share on other sites More sharing options...

broke Donating Members 229 Member For: 13y 4d Gender: Male Posted 04/05/12 04:31 AM Share Posted 04/05/12 04:31 AM is there such a thing as a dump back system? like changing out the cats for high flows and then new stuff from then on? just about everyone ive been talking to about modding has told me I should go exhaust even though im not chasing big power. but some extra noise would be sweet.

You can also cut out the center muffler for a bit more noise but if you can afford it a turbo back exhaust would be much better.Just have a quick flick through the exhaust section.

broke Donating Members 229 Member For: 13y 4d Gender: Male Posted 04/05/12 04:52 AM Share Posted 04/05/12 04:52 AM cheers, rbjet. basically the only mods ive got planned was the exhaust and injectors. tune as well of course. perhaps a batt relocation and turbo side intake for some more spool noises. I'll have a good search though. thanks again :D Link to comment Share on other sites More sharing options...

Henz Tampon inserted, Auto Acquired, next purchase a new handbag Donating Members 9,946 Member For: 16y 6m 28d Gender: Male Location: Vic Posted 04/05/12 06:19 AM Share Posted 04/05/12 06:19 AM I have a 4" dump and 5" cat, and have reached its limit at 16 psi/360rwkw. This is where Tonyv found the limit of it also. As well as worm. If your in SA over 400 is possible. 1 Link to comment Share on other sites More sharing options...
riptide Member 733 Member For: 13y 9m Gender: Male Location: Auckland, New Zealand Posted 04/05/12 06:49 AM Share Posted 04/05/12 06:49 AM I have a full exhaust but I was thinking of putting the back half of the original back on. I find in the early morning (6am) the car is too noisy to let warm up without rattling the neighbours windows at idle. Was going to suggest he get his windows fixed but not sure how he'd take the suggestion.After reading this I might stay with the full system for now. Not into constipation.
