Now I know I am biased posting here but we are very proud of our exhaust system. Full T304 stainless piping, tuned resonators for the engine and chassis, MLS gaskets, all stainless steel hardware, machined step-nuts for ease of install and the works. That coupled with a lifetime warranty and we are happy to call this ours.
And as of today we now have the full turbo-back available for order.
It's our hope to support all the trims and chassis but we are still far away from anything for that model anytime soon.Do you have plans on releasing anything for the EX-T coupes? Please
Yea. Sorry. I take it back.Since when? They have the secondary o2 delete...........when did they stop it? Last time I liked under the "mod" drop down menu it was there......
Yes, Honda is showing a 30 horsepower potential variance across the different models of Civics. These cars have high compression and good potential. From the lower trims with their smaller pipes and chambered mufflers up to the SI model with larger pipes and large chambered mufflers, power goes from 170-ish to 200, but when you take out the chambered mufflers and put in straight-through the engine finally wakes up, tone is improved, and the manual cars are easier to drive. The resonators are fine from factory but as part of smaller diameter pipes can restrict. The horsepower curve is shifted upwards definitely. You can follow the secret to better scavenging too by going from narrow pipes near engine to larger pipe and then reducer cone at tailpipe for max scavenging and horsepower potential.Does anyone actually know if you go striaght pipe/one muffler delete/ resonator delete that you will lose or gain hp/low end tq?
This was my understanding of the straight pipe. You only get sound.LOL, there will be NO increase in performance from a muffler/resonator delete, it is just for sound, catless DP there can be UP to 30hp but NOT from the exhaust.
PRL make and sell downpipes so don't ask them how much power a Greddy or Injen exhaust will make. Try again.I thought that write up was sarcastic the entire time lol. I agree power is in the downpipe, especially under 400 horse. PRL tested this theory already.
Hi there. I think the answer depends on the end user because aftermarket exhausts all flow better than stock so it comes down to what kind of noise you like. The Hatchback Sport Greddy is a single muffler and offers far more sound than stock. If it ever seems too loud you can add a 14in Ultraquiet Vibrant resonator in the stock location. You will have 3 in exhaust going back for faster turbo spool and flow.I really want to get the GReddy exhaust for my 6MT Hatchback sport... I’m driving with the windows down and I can still barely hear the stock exhaust lol. With windows up it’s silent... Anyone have regrets with their Greddy SP?
