I see from your signature that you've changed the TB with a 06+ TSX one ? Did this mod worth the money ?
Is the 06+ TSX TB the same like the 06+ Euro CL9 , any idea ?
And about DC headers, did this mod introduce more noise (aka exhaust noise or something like that) compared with stock ?
Do you have test pipe or high flow cat, or oem cat ?
alraight bud not to sure on actual gains with the 06+TB and IM as i had no base line dyno for comparison, once installed the engine felt slighty more free reving and it felt a little quicker but were not talking massive gains up to 5 HP at best i would say i got the components imported from the US from these guys (http://oemacuraparts.com) after import tax i ended up paying just under £450

these prices are a bit higher than when i got them.
The 06+ TSX got a whole bunch of subtle revisions including, slightly better flowing intake mani larger bore TB, slightly wider exhaust, better flowing head design and a revised intake cam with slightly higher lift and longer duration all of which pushed it to 200hp vs the pre-facelift 188. unfortunately Honda did not see fit to carry these revisions across to the european and Jap CL9s so engines in 06+ Accords are the same as those in the prefacelift accords and the pre facelift TSX.
The DC sports mani allows abit more of the engine noise to come through vs the stock exhaust mani but its not loud or intrusive, you can hear the engine revving nicely. At the moment i have the oem Cat on though once this intake arrives ill be getting a higher flowing cat installed to keep it legal, ive seen to many road side testers to risk a test pipe on public roads.
Hope this helps inform a descision buddy
Edit: H&Rs are set to softest though i may adjust the rear to the stronger setting soon just to see what the difference is
