Just wanted to see what you guys are running for a 3 inch catback and which one would be best. I need to put bigger long tubes on the car, and go 3 inch all the way. weird dyno day today with my 3.0 whipple.
Bassani is like the only 3in i know of....think also Magnaflow made one?
I'd take it to a good exhaust shop and have them custom one for you. With how expensive catbacks have gotten with inflation pricing, honestly a custom job might even come out less.

i ordered mine in june of 22. they shipped 4 months later almost to the day. i feel for you. that 4 month wait was tough even though the car was just sititng.whats up guys. Dont post much but wanted to give you an update. Going to keep the 2.5 catback. will not make a difference going to a 3 inch catback unless we are going to make over 1000rwhp and want to squeeze every bit out of the car. I ordered the 1 7/8 long tubes with x pipe from ARH. Get this. we ordered this in the summer and I still have no ETA. Its march lol. Going on 8 months. No headers. crazy times we live in.
But should be interesting if I see any gains. was told I should pick up power throughout the whole power band. Not loose any tq down low. Hopefully I loose some boost pressure. I want to throw back my lower pulley. since we removed my 4lb lower, the car lost tq. I am seeing 23lbs at the very top of the pull. stock size lower. I have to see what upper is on the car bc we were swapping pullies like crazy with the 3.0 to bring the boost down. at one point we saw 27lbs and it wasnt even a full pull. If the boost drops with these long tubes I am throwing on at least a 2lb lower. spin the blower up a bit quicker should make more tq.
And for the FK of it, I am also talking to todd about custom cams for my car. should be interesting
Can you let me know what size upper you have to make 23lbs with a stock lower?whats up guys. Dont post much but wanted to give you an update.

yea its crazy. 8 months and I cant even get an ETA. Our goal was trying to install and dyno the car with the cool weather. Bc when we did the 3L whipple, it was BOILING outside. so we wanted to tune the car with the bigger headers in a little cooler weather. Guess that wont happen haha. so while I am waiting todd warren and I are going back and fourth on cam ideas.i ordered mine in june of 22. they shipped 4 months later almost to the day. i feel for you. that 4 month wait was tough even though the car was just sititng.
Sweet, thanks. I’m shooting for 25-26lbs with a 3.125 upper and stock lower with 1 7/8” longtubesNot a problem. I have a 3.375 grip tec pulley. Im seeing 23lbs at the very top. My car does need a lower pulley. even if I dont drop boost im still throwing a 2lber on there with the 3.0 whipple. Id love to throw back my 4lb but 27 lbs is ehhh. on a stock motor. The 3L needs to be spun. My 2.9 was more responsive when driving around town. Lower rpms.
anytime bro. yea thats the boost range I want to hit as well. 25lbs. Im going to bring a 2lb and a 4lb lower with me.Sweet, thanks. I’m shooting for 25-26lbs with a 3.125 upper and stock lower with 1 7/8” longtubes

yea I thought about that as well. Thats why I might do my cams and headers at the same time since its been 8 months. You are 100% correctJust remember, your boost pressure is what’s in the intake.
Increasing exhaust flow can reduce boost pressure, but not cylinder pressure.
