slash just helped me throw a garret t3 on my dohc neon and now my problem is that I deleted my catalitic converter and the exhaust places wont touch the car to finnish the downpipe because there is no cat even though we're not an emissionsmandatory city. So i'm wondering if i'm stuck with going to flex pipe route.

RE: turbo downpipe question
I was talking to a back yard exhaust specialist guy today and he quoted me $150 for a 2 foot custom section of pipe that connects to my stock 1 ft of pipe from the turbo to the end of where the cat used to be i had him clamp my exhaust flexy pipe back up and I was out of there. before i left he told me he used to work for midas and that their policy was to call the dnr and the police to impound the car or have it towed out of there unless all the emissions were put on as normal. he also laughed at slashs quick fix flex pipe job but hey it works. for now.

it really sucks because the exhaust guytook my flex pipe off to take a look at whats left of the original downpipe and he must have put it on loose so i'd get smoked out because i still have a severe headache from after i left his place and i smell exhaust hardcore. so i guess i'll have to jack it up tomorrow and redo the clampsm

I would get a flex pipe just because it is better, then get a high flow cat, from carsound.com.

Their is no, zero, zip, nadda gain from using a staight pipe over a high flow cat. Plus it will not be as loud, and will help the enviroment.

my cat was clogged big time it wasn't an option weather or not to use it the only option was to take it off. I'm using flex pipe right now almost 2 feet of it just gota find the leaks from when the guy took it off. my car is alot more quiet with the turbothan when i had the pacesetter headeron it its not loud until i take it up to 5-7,000 rpm.

by removing the catalitic converter your turbo will spool faster because it doesn't have any resistance, its not a whole lot of resistance but its enough to take away 500rpm of your spool time on the low end. besides theres enough tofo fartin fairys driving hybrids to make up for my neon without a cat.

i cut off my cat too, and now have revised my thinking to put a high-flow cat on when i get my new exhaust. no cat vs high flow = not enough difference to be bothered

you dont have a turbo so you can be smug about it saying its not enough difference. its not about gaining horsepower as it is gaining spool time which could be the same as gaining powerin the powerband on a turbo application

The over thing, most cats don't last with a turbo set up. The extra heat melts them. Atleast it does on my Honda.
