I currently have a 2008 ss/tc, i am running a stock down pipe with muffler delete i have HAHN intake, and dejon bov spring, Want to do a cat less down pipe but am very scared that its gonna sound like ****. Does anyone have this done, vids, or sound clips would be appreciated. Recommendations/Suggestions welcome.

 

i have the hahn exhaust and their catless dp. i LOVE the sound of it! its not bad at all. it gets loud when i get on it but not obscenely loud. just a nice roar.

 

I have NO exhaust i cut the muffler out and welded in a pipe!

 

OR if you are unsure you can get the Hahn "MOD Pipe" and get the "cat less/straight pipe version"

If you dont like it you can then just buy the cat later, and you can swap them out as you like...

The non catted DP by Hahn does not throw codes either

 

did you notice any differance with the spring?

 

just curious can you hear the turbo in the exhaust with the cat less dp

 

should be able to

 

Yes you can

 

YES! Myself along with two of my very good friends have ss/tc's (i know its cute/i had mine first) i did the cai and spring, my one friend just did the cai, the sound is soooooooooo different the spring makes the bo soo crisp, where with the stock spring kinda has a funky sound to me both sound good but i like mine better! Actually sounds like a aftermarket bov. OOO and other friend is still stock. lol

 

yeah you can hear it more. my Gf who has no clue about cars even said the turbo is a lil louder with the catless dp. lmao!

 

Someone said it sounds like an srt4 which i dont think is too bad of a sound i just dont like the rasp sound in high rpms

Since its a daily driver im only putting intake, muffler delete, intercooler piping, and tune, and considering a down pipe (Catless, NO inspections where i am)

How much of a sound difference is the catted vs cattless?

 

i have it done on my car unfortunetly the day i was gonna record my video i discoverd a blown turbo but it sounds good you can hear the turbo in the exhaust inside the car its not loud at all but next to walls or in tunnels its loud as hell i love it and cant wait to hear it again

 

WOW im sure you posted but how did you blow the turbo. im guessing chevy isnt replacing it lol sry to hear that

bump anyone? vids sound clips

 

yeah ive posted a coupke of times but it doesnt bother me it seems that a peace of metal was left over during the construction of my intake and it broke loose and my turbo didnt like that much i found the peace of metal in the inner fins of my filter all chewed up aswell as the fins on my turbo....i didnt even try going to the dealer for it i didnt feel like getting thrown around or anything so im just gonna go with BTF Ko4+ upgrade its cheaper then getting a new turbo plus it has better flow

ill be able to put a vid up in a week or 2 when i get my new turbo

 

i had custom exhaust work on mine i used the stock resonator and cut the end off a little then welded 3in to it. exhaust comes out in front of drive rear tire. it not sound bad at all.it real loud when i get on it. but that just my racing exhaust i going to have it go all the way out the back too. make it with some v clamps so i can change it out in like ten mins.

 

DEFINITELY keep us posted@!

 

oh i will im taking my turbo off this saturday and shipping it to Rick on wedsday and we will see how it goes from there

 

damnit i think i may just do it nd have to post vids hopefully someone will reply i would like to hear it first!

 

look in my thread about ss tc pics and vids search that

 

lol i ment performance wise lol some people on the thread for it were saying they thought it held boost better but it is good to know the sound quality is better too

how many lbs can you boost with that turbo wheel upgrade i was hearing people say 25 is suggested for best performance...... compared to 21 stock

OoO sorry im still close to stock but yes the bov spring upgrade for only 10 dollars, there is much better quality it is a lot stiffer and when i get some more mods and get tuned it will hold boost better, THE MAIN REASON I DID IT WAS BECAUSE I BOUGHT THE COLD AIR INTAKE AND ITS RIGHT THERE NEXT TO IT I KNEW IT WAS A MOD I WAS GOING TO DO SO INSTEAD OF INSTALLING THE INTAKE AND HAVING TO GO BACK AND REMOVE IT TO INSTALL THE SPRING I DID IT ALL AT ONCE.
