tsudo isnt very bad actually. its smog legal and gives ur car a deep heavy tone thats also not too loud here in cali. they not as popular as greddy or apexi or hks but its just one under all the major "big boy" brands. its not very popular cus its kinda of hidden amidst greddy, hks, apexi, magnaflow, etc... i had a tsudo exhaust on my 93 accord se and before that i had a greddy. my car was stolen and stripped so the second time i went for something cheaper, and i didnt feel a huge difference in the Tsudo exhaust from the greddy, same HP increase.
