I am finishing my bolt ons for my car. I have all the bolt ons, clutch, and radiator/ic upgraded. I was wondering if I will be fine to get the midpipe to finish up my bolt on list. I know that a lot of people talk about boost creep and everything, but then again there are some saying they don't have any problems.

Like you said... some people claims no problems... others do.

My opinion: If you have a stock ECU and turbo wastegate it's best to keep the cat converter in place if you want your engine to last.

Yea, I have stock ecu still and wastegate. That's what they were saying to do, is port the wastegate, but even that is a lot of money and I don't know if the performance gain is worth spending that much money?

No, IMO it's not safe with just bolt-ons. The topic has been covered extensively, especially since they started selling inexpensive DP-MP combinations on ebay. You would need to port the wastegate. But if you want to give it a try anyway, it's your car. But remember that you've only heard from the guys that have been (IMO) lucky so far. The others who have blown their motors from creep are probably not as likely to post up those experiences.

I have a street ported engine, efini twins, air intake downpipe and cat back. Is getting a mid pipe safe in this case? or shoiuld i look into an aftermarket ECU?
