Looks Good. You need to get a better video though! Maybe one with a WOT drive-by, or some higher revs at least.
How much did that whole system cost??

Thats a little steep on the install i think, but I am sure it was well worth it to you!
When you get another vid, you should get one of your brothers car too! I wanna hear that side exit.

That's got a pretty good idle note. I can't really tell on the throttle notes, I need a drive by and or better quality video. So far from what I hear it sounded pretty "meaty".

Re: 305tpi new cat w/ chambered muffler
the welds and the quality of work looks real nice.
but i don't if its the video or what. i need to hear more before i would really want to comment. i don't want to say soemthing that will be wrong.
i like the idle too. but i need more.
looks great though.

Re: 305tpi new cat w/ chambered muffler
Hey, Cali? I noticed you had another 2 videos of your car on youtube? Are those with the powerstick too, or something else?
I really like the "New exhaust TPI" video, where the camera is on the ground behind the RR corner of the car! That sounded killer.

Re: 305tpi new cat w/ chambered muffler
So I am guessing your brother's sidepipe sounds kinda like those videos, huh? I really need to get my muffler off one day to see. I think I need a can of better penetrating oil, like PB Blaster or something. I will soak it in PB every day, eventually it will loosen the rust lol.

Re: 305tpi new cat w/ chambered muffler

Yea, I know they have them in all different lengths. Thats why I asked what length tube you ordered, and put in yours?

Re: 305tpi new cat w/ chambered muffler

Re: 305tpi new cat w/ chambered muffler
Why would you get 2.5" pipe? Was the 3" that much more expensive?

Re: 305tpi new cat w/ chambered muffler
i'm still debating on using these for my true dual build since i like my single 3 inch sound, or else i'll go ultraflo's from dynomax. I dont think i could go wrong with the powersticks tho
