My DCRH whistles aswell. It's normal I think, indeed it comes from like inside the manifold itself. Remember the cat is gone, so less sound gets filtered.
Just put on my tegiwa 4-2-1 this weekend and it's great apart from a slight tinny/whistle noise it has. It has no leaks on any joints or any holes or cracks. It just sounds like it's from inside the pipes. Is this normal??
TBH I have notice a massive difference. I didn't think it would make much difference before I get it mapped but it has. It pulls harder in vtec and picks up better between 4500 to 6000. Just ordered an tegiwa gruppe m replica induction kit so that should also help.
All the pipes are exactly the same length on mine. I'm very pleased for the price of it
I used a L shaped adapter and done over 500 miles with no engine light as yet.

It did look like it was uneven so I measured it all and all good. The old manifold looked useless compared to the new one. Thin pipes and nipped in so it fits in the one.
You guys that have bought the TODA replica header; You've all got JDM front ARB's and uprated engine mounts havn't you ??
It look a lot of finding that L shape adapter. It came from Canada.
Suits. I have the jdm FARB but no engine mounts as yet. Any ideas on the engine mounts?
