can i summarise by saying:

dont get an open pipe for ur street car for two reasons:

1. u will lose power in the low rpm range, for the reasons mentioned before, some small gains in the high rpm range

thats pretty useless since its a street car, and for u to really feel a difference ud have to be living in vtec for ever, this creates all kinds of issues

but since i assume u drive normally most of the time, u will appreciate the power loss ALOT more than the power gain

2. Its illegal for street cars to run an open pipe

10k fine

environmental filth

and most likely ur car will smell like a broken lawn mower leaking fuel forever
