So I just installed a ZZP catless dp tonight, and holly ******* **** is the car loud! Granted I have a 3" side exit cat back as well, which is relatvely loud to begin with, but oh my god it is rediculous now. The turbo sound I get when I'm just cruising sounds freakin sweet, but when I go WOT... YUCK... I'm going to put the stock exhaust back on tomorrow (minus the stock dp that is, I'm lovin the ZZP dp) and hopefully it will sound a little less like a car with a broken exhaust. Any thoughts on how that will sound? Will the full stocker be too restrictive?

 

I run Catless DP With factory exhaust and IMO I think it is a perfect balance of loudness when you want it and softness if you don't , It has not been too restrictive at all for me .. Sounds good

 

any sound clips

 

catless DP with muffler delete = sexxxxx

 

yeah I have been debating this but I have a feeling with no baffle in it you will get that ricey raspy ricer sound then you gotta weld the damn muffler back on if you don't like it ..

 

I'll try to make some sound clips tomorrow before I swap exhausts. If I hated my neightbors enough, I'd go ahead and make some clips for you tonight..

yeah I get that super raspy/broken exhaust sound with this setup so I be worried about the same thing with removing the muffler.. although maybe not seeing as how the stock piping is only 2.25" in stead of the 3" I have.. ehh I don't know

 

its not really the 2 inch pipes you're running which are more then enough to flow for a 300HP turbo car , its the cats in the stock downpipe that are the restrictive part, I think the muffler and catless is a perfect happy medium .

 

yeah I'll be trying that combo tomorrow either way, so I'm sure it will be leagues better than what it currently sounds like. Plus I won't have a stupid big gaping hole in my rear bumper where my exhaust tip once was..

 

yep it will be loud. lol what did you expect?

 

I'm running the ZZP catless DP on the stock catback. It's just right...except at 4am in cat warmup mode.

 

to all the people that think their car sounds good from inside the car....give your keys to a friend and let him pass you at WOT

 

damn man.. lol i coulda told you that .lol.. but ps the stock exhaust is 2.5 "

 

Trusting said friend with a car they cannot handle is a very good idea. expecialy a wot pull

 

Just sayin. I thought my car sounded amazing from the inside, then i let a friend drive it and was like eww

 

any pictures of the exhaust? or sound clips?

 

can only help catless 3in so much.

 

I'm running a catless dp and a full 3" all the way through. I have a muffler but no designator or anything and I and everyone I know likes the sound. I had a buddy of mine record a WOT pull and I like it

 

Catless with a muffler delete sound real close to this. So if you want quiter make sure you have a muffler.

 

hey where did you order the side exhaust and was it easy to install??

 

If you're not running a larger turbo...then no...it won't be too restrictive at all...and it'll sound sweet as hell.

 

i approve on the muffler delete and catless dp.....the ss/tc sounds sweet like that

 

lol.. yeah I knew it would obviously be loud, but this just sounds like canned ****

nope.. the exhaust is 2.25 ID.. it's 2.5 OD but who cares about the OD measurement for exhaust piping

I'll work on getting a sound clip today.. it really sounds sweet when just cruising around and you listen to that turbo spool, but other than that... yikes

it's a Jennetty side exit, and yeah it's super easy to install.. the longest part is deciding where oh where to make the cut on your stock exhaust just in case you might need to reuse it at some point.. it sounded great with the stock DP just not catless

 

Reduce the Spark Advance in the ECT SA Table and that goes away



To the OP: I run the ZZP DP and stock exhaust and I like the sound a lot. As others have said, it's a good mix of quite and loud! You can make plenty of power using the stock exhaust also

 

um i was thinking of doing 3 in side exhaust on my swapped turbo lsj. the dp has a cat. but dang idk if its going to be too loud now lol

 

ok sweet.. I trust your oppinion, and I will know for sure later tonight when I do the swap. Can you still hear the turbo spooling through the exhaust at low rpm? That is by far the coolest part of this setup.. not cool enough to keep the side exit on though imo
