Tsp stainless vs. Bbk on install and fit
Thank you so much
No experience with BBKs but I will say the ARs I installed went in easier than the factory manifolds and only required removing the dipstick tube. The set I removed from another car almost fell out...
I did NOT have to remove my starter. I really don't know where these nightmare installs come from. As far as sliding them in and out, it's really easy. If you can change oil, you can install headers.
The steering shaft is just 2 bolts. Is that hard? Did I miss something?
In the end, it's up to you. Do you want 1 3/4" primaries and a tiny 2.5" Y, or do you want better gains with an 1 7/8" primary with full 3" Y?
Do it once, do it right.

Go to the dyno section. Look at the graphs. 1 7/8" makes more power. Period.
I'm sorry guys. I know I'm coming off as a dick. It's not intended to be taken that way, but fact is fact. The information is out there. Just read it.
Even for a stock 346.

Even tsp's test of their 1 7/8ths headers only had 7hp over 1 3/4 pacesetters on the dyno, and thats on an engine dyno on a chassis dyno you would never even notice that.. https://ls1tech.com/forums/generatio...o-results.html
Also I'd love for someone to post up a dyno slip back to back on the same dyno comparing the bbk y to a larger one. The reason being is that the bbk merge is better than some aftermarket 3" pipes and that alone would help power. Second, and this is my biggest point is that you're stuffing two 3" pipes into one 3" pipe? How can you say that its going to flow any better than two 2.5 pipes into a 3" pipe. A bolt on ls1 as a whole cant really use a bigger pipe than 3" to effectively make hp (4" mufflex systems dont make much more than 3" systems) so why would you need one of those on each side of the motor for the y pipe?
Again I'm not tryting to be a dick either but saying 1 3/4 headers are insuperior and that the 2.5 is tiny for an ls1 is somewhat misinformed.
