So sometimes when im driving and i change gears or i step of the gas i hear a like a pop coming from my exhaust ...(hks hi power 3 inch) ... Anyone know why??

I wanted to try out an ebay intake on my t28 2g dsm .. the results are it looks verry nice and the bov sounds louder too.but i dont feel the boost i used to on my stock set up.. i tought it might be a leak but i check everything already.. any help

So i wanted to take out the wgs restrictor off of my 2g gsx.. so i took every step and did ### im supose to do but when i didnt find anything inside the tube.. dont even know ### it looks like or anything .. or maybe the previous owner took it off already i dont know ... Any help with how it...

Ok so im going to change my spark plugs soon and a question came up as i was discussing these with a buddy of mine.... Ive been using the stock copper plugs on my 2g gsx n i was wondering if using iridium ngk plugs perform better on turbo dsms or should i keep using the stock copper plugs...

Im in the LA area and im having trouble finding a good shop for dsm that can help me in performance modifications.... Any suggestions??
