I wouldn't entertain taking the twinscroll away tbh, I love everything about it to be fair the lm450 makes an awesome noise on boost don't want it much louder I have to be honest, but would like a little more which I why I'm thinking to try a different non resonated center section to perhaps give me that little extra, what would you guys say to try first, a smaller backbox (not so bulky) to get a bit more noise or the center section? My thoughts would be center first as I don't want it ludicrously loud as my neighbours hated my uk Sti lmao, but that was proper loud and had to start it every morning at 6.20 before I left for work, fair to say they have all commented on how quiet this one is but lucky for me even the older generation who live around me are quite in to their cars or had been previously, so they have some understanding lol, I pick one of the boys up on the way in to work who lives the other side of the village, and on the uk car he would hear me starting it, he would leave his window open so he knew when I pulled away to meet me at the top of the street, so don't want to be going down that route again as I do appreciate the quiet long distant drives, so just want something that will offer me a bit more but not over kill, any suggestions welcome

 

just had vf34 installed making 290 torque 312 bhp at flywheel. pulls better through gears though. we are lacking another 20 somewhere, plugs? headers? fuel might of been low causing it to warm. any ideas anyone....

 

Your mods?

 

Is it decatted?
FYI The Gimp runs 482bhp on meth on his car with an RCM 100 cell sports cat. If you buy a decent make you can still get the performance

 

Steve no offence mate but it might be better to start your own thread on this as opposed to hijacking this one!
Also see the thread started by chet123 who had similar issues with his.

 

650cc top feeds on a buy it now on eBay for £160 would recommend Harvey up pipe but becoming like gold dust though have seen a few 2 bolt ones alternatively rcm ones come up for only £50 on here quite often. for turbo for sheer versatility ie instant boost and good power has to be the sc36 billet. I currently am running a vf 34 it will give you the power you want with low down punch and also at the top of the range but given the choice would go sc 36 billet every time if given the choice.
