_shaun_ Posted March 10, 2015 Share Posted March 10, 2015 It makes no odds really id probably go for the hks for extra scene points tho Quote Link to post Share on other sites
Lukee Posted March 10, 2015 Author Share Posted March 10, 2015 It makes no odds really id probably go for the hks for extra scene points thothats what i was thinking lol, so it wouldnt really affect it no?im td04 230bhp Quote Link to post Share on other sites
_shaun_ Posted March 10, 2015 Share Posted March 10, 2015 you might get a change in tone of the exhaust but shoudnt effect power in anyway its really the exhaust pipe size that can be restrictive but shouldnt really have any issues with that till you change far bigger boost.

Lukee Posted March 10, 2015 Author Share Posted March 10, 2015 yeah can barely hear my exhaust now tbh, apparently this hks one is abit louder, ive got 3.5inch all the wya through till the backbox so not restrictive trbh lol okay awesome thanks for your help mate, only 0.9 bar so not much at all Quote Link to post Share on other sites
_shaun_ Posted March 10, 2015 Share Posted March 10, 2015 3.5" striaght though you sure? the biggest ive seen was 3" and on a starlet clearance was eh close! theres a few difference hks boxes some have removeable baffles and can be fairly loud Quote Link to post Share on other sites
Lukee Posted March 10, 2015 Author Share Posted March 10, 2015 oh sorry 2.5 lol , getting carried away!! erm yeah i kinda got no clearence and made scalextrix marks on the floor when i went td04, downpipes are so long! and awesome, not sure which one i think its the HI-POWER, or something?

_shaun_ Posted March 10, 2015 Share Posted March 10, 2015 ha i was thinking that. every starlet ive ever owned has had the flexi scraped to hell on even the smallest system. they do hi-power and silent and what not am not sure if the difference is just the back box or there totaly different exhauts ive never made that much attention to them to be honest Quote Link to post Share on other sites
Ollieh17 Posted March 10, 2015 Share Posted March 10, 2015 Just back box or full system? Quote Link to post Share on other sites
Lukee Posted March 10, 2015 Author Share Posted March 10, 2015 i got full JPerformance system, but got a hks hi-power backbox i could put on lol Quote Link to post Share on other sites
