i got the full INJEN upper, lower, and intake fitted in my car but the couplars are blowing...? running stock boost on fwd. it doesnt feel like it lags whats so ever. when you just floor it, it just pops. early fall, i had my lower turbo couplar pop. the car just stalled, gasped for air like a dying horse so i pulled over. popped the hood and their it was loose lower hard pipe from the turbo(black j pipe).

i need help figuring out which size clamps to buy to fit the injen setup i got?!!

your welcome!

ps. I want to say the turbo>intake coupler is 2.5" but you dont need a t-bolt there obviously.

 

those are only for stock setup. those would fit my aftermarket pipings...aren't they bigger..?
