YouTube - Zzp catless downpipe stock exhaust 09 ss/tc



love the sound with stock exhaust

 

sounds good. bpv is pretty loud as well!

 

looks slow













jk jk, sounds awesome!

 

sounds just like mine lol you gonna do exhaust or muffler delete?

 

sounds good..... at least another person reppin a zzp

 

I rep ZZP huge

 

humm i like. where do you get this upgrade spring for the bpv?

 

it does sound sexy that bpv

 

thanks yeah i love how it sounds right now but im sure ill get bored like always and not sure what i want to get with exhaust wise yet. for the money i feel zzp is the best and the quailty is great. dejon has the upgraded spring for like $10

 

sick whats the benifits of it?

 

it holds up better to higher boost levels pretty much. pretty much its a thicker spring. i wanna get the forge motorsports bpv

 

souperman is that what ur running?

 

yeah just the dejon upgraded spring and dejon sri with the tune

 

Sounds nice

 

Did you get tuned for the BPV Spring?

I see that the website says

So to me, I should get one for that reason alone, but I'm not tuned for it so hmmm....

 

cool ill look in to that i ran into someone with it the blow off sounded louder that the stock. he was gms1

 

i first got it when i was on gms1 and it sounds the same then as i am now with it being tuned. but when i got tuned i mentioned that i had that and he said he tuned me for it. it sounds A LOT better then the stock spring. for $10 def worth the investment and takes 2 mins to install

 

sounds really nice man

 

So you're saying you had it (spring upgrade) on GMS1 and you had no problems, and it sounded like it does now in the video. Then you got tuned and it sounds the same, but much better or since you're pushing more boost it sounds better than it did with just GMS1?

Basically the only thing I'm concerned about is can I put it on without tuning for it, from what I'm understanding from this post is yes, yes I can.

 

yeah i had no problem with it when i was on gms1 tune 20psi and what im at now at 23psi.

 

I<3 my zzp catless DP! Enjoy!

Thanks for sharing this info!

 

enjoy man and no problem

 

Hey Souperman, was it an easy install?
