Can finally upgrade the catback on ttop350. The smaller SLP exhaust has been on there since 1991 and is a bit of a choking point for my "stock" 350 engine ;-)
Hawks new totl catback. Hope to install it when i get some time soon. (the old SLP catback isn't the one from my car)
Hawks black box of goodness arrived yesterday Old slp 3" x2.5 tails stainless and the new 3.5" x 3" tails side by side Old tails and new tails My friend Marty picked up a couple for his cars
I saw this and wanted it but that price is just unjustifiable for no power gain, all appearance over the 3.5” exhaust I built only a couple years ago. I expected it to be in Borla territory but NOPE!
Haven't had a chance to touch it. I think I'm going to upgrade my 20yr old temporary Y pipe to stainless and get some slip fit sections to make this all the way i want it.
itll be a bit.

Yeah, this isn't really for a stock ish engine its really more for the 600hp and up crowd. Maybe ill get there someday 😆
I wish this system had a 4" section before the muffler. I'm super curious to see N/A combo Dyno results. My dual 3" is beautiful, but murder to drive.
When i 1st spoke to Bruce about my idea several years ago, thai told him i was building a setup like this with a 4" intermediate pipe and still dual 3" out. (I have it partially done).
we discussed the reasons for 3.5 vs 4 and it came down to power gain, cost, fitment and extra weight.
The gains from 3.5 to 4" were minimal if any on his higher hp cars. Ls swapped blower setups.
Hawks posted a sound clip of the new TOTL exhaust running on a cammed LS3 on their instagram. Sounds really good - might be a little loud for my taste at higher throttle, but I think I'm sold when it comes time for my swap this fall- originally wanted to go hooker blackheart but the headers being discontinued made that more of a challenge.

Yeah. That was a real shame. It prompted me to arrange to preserve my current headers by going for a ceramic coating. And I can always do what TTOP has to do now and everyone else going forward and that's adapt whatever "cat back" you decide on and integrate that with whatever headers you've got (or get).
With a bit of luck, this Hawks deal's intermediate pipe might line up in the same space as my current Edelbrock single 3" does. It'll save some fab work as I've invested (heavily) in a Y-pipe to fit my current setup.
I'll wait for Mr. T's installation pictures. I'm in no rush...

I called and spoke with Stainless works today about parts i need to upgrade the 20 plus yr old temporary Ypipe to stainless.
Cut, sectioned, and tucked the frame rails. Modified the factory Xmemeber to run dual 3" slip fit from headers into a single 3" to the SLP catback. Going to build a stainless dual 3" into a single 3.5" to match the SW catback.
What I hope is that I wouldn't have to invest in another one of these.
From a collection of 2-1/2" Y-J stainless bends from Vibrant. Then Tigged together with Magnaflow's 2x2-1/2" into 3" merge. It's part of a complete system now from the headers to the tailpipe plus a modified OEM crossmember so it's tucked up as tight as possible.
What's your take on the straight out the back look vs the tucked up and down turn approach?
I like the downturned idea but my friends have taken to calling my car the "leaf blower". I think you know what I mean.
I've always liked a more heard not seen approach when it comes to exhaust.
The 4thgen totl has the straight back pipes which look good on that body style.
your friends are jealous..... lol

I ended up getting the "factory style" dual downturn tip stainless works exhaust for my build, since 3.5" for the totl would be overkill for a stockish LS1 imo. hit my door today, I was more than a little disappointed to look in the first piece of tubing I pulled out of the box, and see that they did not back-purge the welds, and the inside has quite of bit of sugaring. I would have thought a professional stainless exhaust builder would back-purge everything.
For anyone who has this exhaust, i'm curious if it is overkill for a stock TPI? My future plans are a HCI 355, and i love the look of the TOTL. Anyone with any experience yet?
Man can you post a video of the sound clips from that system, I am looking for a stainless exhaust for my 25th z28 TPI, Can find 0 sound clips of most stainless exhaust systems on a 350. Everything is ls swapped which is sad. Was debating the Borla system, hard to drop 2k on a exhaust you cant hear but if you can post a sound clip man i'd really appreciate it.
