I have 60 mm piping exhaust w/ JDM header & test pipe. I was thinking of re piping it to 2.5, but still, wouldn't there be a bottleneck where the piping meets the muffler? Would that be just as bad as not doing it?

By the way I have JUN stage 3 cams, Springs, Titanium retatiners, DC JDM 4-1 headers, 2.5 testpipe, and a Tanabe G Power exhaust.

Thanks again

 

no real point since you still have the small header.

What muffler are you using?

 

Waste of $

 

I have the DC JDM type-r header which comes w/ a 2.5 collector and for the muffler I am using a Tanabe G Power cat back.....

In away I am hopeing it's a waste of money, so I don't have to spend money on modifing the modifications hehehe

if you dont wanna spend the money then dont. its as simple as taht

 

True, but I will spend the money if it's worth it. Don't get me wrong, I will spend the money, but if ya'll feel it's not worth the time or money, than I would take another route or not even bother. That is why I am asking you guys this question, I am way sure that you guys might know more than me, (lol...obviously), when it comes to NA engines and the way air flow is very important.

I was just unsure if there would be a big difference in power and if it is worth the money or change the whole catback to something else that has the pipings required....
