i've got a jjr screamer on my highflow turbo, Look i'l be honest with you guys, Just like what others said......
- No HP advantage
- illegal
- LEAKS ON IDLE. JJR ONES LEAK 100% , IF U WANT A GOOD ONE U CAN GET AN EXSPENSIVE ONE FOR LIKE 300 & THEY DONT LEAK.
but but, I love it, sounds crazy!!!!!!!! in the videos thats what mines sounds like! even sounds better with the cat bashed out, more holow... but yeh, i'd personally dont recommend it.
