Is the stock Type R B Pipe suitable for my setup? I'm shooting for 180-200whp on this b18c1 with cams 10,5,1 CR , PX Intake and lots of extras. I was thinking the OEM ITR 98 spec mid pipe would be a nice choice since it has three resonators instead of two like the 96 spec did or even worse just one resonator like the Spoon or T1R B pipe. I'm trying to keep the sound level down via the B Pipe section since I plan on using a test pipe and the N1 muffler. If the stock ITR b pipe is going to choke my setup, I'll put out the cash for the spoon mid pipe. I want to get everything in place before I get my Hondata tuned in a few weeks.

Exhaust set is going to be
98 spec 5 Zigen Type R header (Jet Coated)
T1R JDM length Test Pipe (Jet Coated)
98 spec OEM Type R B Pipe (Part in question)
Spoon N1 Axleback

Thanks

 

The b pipe on the list of exhaust parts your planning to run will effect flow but not by much.

The parts ur intending on running are a liytle small in diameter and outdated. The lack of cat will cause a raspiness.

My opinion would be to run a yonaka 2.5 with high flow cat for quietness. Or custom 3in all the way back to a magnaflow for whp.

As far as header if u plan on remaining 1.8 then a toda replica or big tube replica if you plan on going larger diplacement in the future.
